The system of inequalities is y < x + 2 and 5y ≤ -2x + 10
How to determine the system of inequalityFrom the question, we have the following parameters that can be used in our computation:
The blue and the red lines
For the blue line, we have the following points
(0, 2) and (-2, 0)
The equation is represented as
y = mx + c
Where
c = y when x = 0
So, we have
y = mx + 2
Using the points, we have
-2m + 2 = 0
m = 1
So, we have
y = x + 2
The lower part is shaded and the line is a dotted line
So, we have
y < x + 2
For the red line, we have the following points
(0, 2) and (5, 0)
The equation is represented as
y = mx + c
Where
c = y when x = 0
So, we have
y = mx + 2
Using the points, we have
5m + 2 = 0
m = -2/5
So, we have
y = -2/5x + 2
The lower part is shaded and the line is a shaded line
So, we have
y ≤ -2/5x + 2
Multiply through by 5
5y ≤ -2x + 10
Hence, the system is y < x + 2 and 5y ≤ -2x + 10

Mr. Shaw is building a walk away from the corner of his house out to his vegetable garden in the corner of the yard. The dimensions of the yard and the garden are shown. What is the length of the walkway, w, to the nearest foot?
A 24 foot
B 34 foot
C 46 foot
D 58 foot
Ummi chose C as the correct answer. How might she had gotten that answer?
Answer:
34 Foot
Step-by-step explanation:
You're basically just doing the pythagorean theory: a^2+b^2=c^2
You just are not directly being given a or b and instead you have to find them which you do by subtracting how big the garden is from the total length: 50-20=30(a) 30-14=16(b). After that you just do the normal theory getting 30^2+16^2=c^2 which leads to 900+256=c^2 then 1156=c^2 so you take the square root of both sides in order to turn c^2 into plain c or the length of the walk way which will get you 34 feet.

For function f(x)= -4x²-4x-1, f(x+h)= -4x² - 8xh - 4h² - 4x - 4h - 1, (f(x+h) - f(x))/h= -8x - 4h - 4
Describe function ?The input values of a function are called the domain, and the output values are called the range. The domain can be any set of values, but each input value must have a unique corresponding output value. If there are multiple input values that produce the same output value, the function is not considered to be well-defined. Functions are used to model a wide range of phenomena in many different fields, including science, engineering, and economics. They are also used in calculus to study rates of change and slopes of curves.
To find f(x+h), we need to replace x with (x+h) in the given function:
f(x+h) = -4(x+h)² - 4(x+h) - 1
= -4(x² + 2xh + h²) - 4x - 4h - 1
= -4x² - 8xh - 4h² - 4x - 4h - 1
To find (f(x+h) - f(x))/h, we first need to find f(x):
f(x) = -4x² - 4x - 1
Then we can substitute f(x+h) and f(x) in the formula:
(f(x+h) - f(x))/h = (-4x² - 8xh - 4h² - 4x - 4h - 1 - (-4x² - 4x - 1))/h
= (-4x² - 8xh - 4h² - 4x - 4h - 1 + 4x^2 + 4x + 1)/h
= (-8xh - 4h² - 4h)/h
= -8x - 4h - 4
So, f(x+h) = -4x² - 8xh - 4h² - 4x - 4h - 1, and (f(x+h) - f(x))/h = -8x - 4h - 4.

The arc length of a single section on a dartboard rounded to the nearest millimeter is 53 mm.
What is equations ?
In mathematics, an equation is a statement that two expressions are equal. It typically involves one or more variables that can take on different values, and the goal is often to solve for the value(s) of the variable(s) that make the equation true.
According to given conditions :The total circumference of the dartboard is given by:
C = 2πr
where r is the radius of the dartboard.
Substituting the given values, we get:
C = 2π(170 mm)
C = 1068.18 mm
Dividing the circumference by the number of sections, we get the arc length of a single section:
Arc length = C/20
Arc length = 1068.18 mm/20
Arc length ≈ 53.41 mm
Rounding this to the nearest millimeter, we get:
Arc length ≈ 53 mm
Therefore, the arc length of a single section on a dartboard rounded to the nearest millimeter is 53 mm.

solve for x. 4(x+56.5)=30x-112
Answer:
x = 13
Step-by-step explanation:
Let's simplify and solve for x:
4(x+56.5) = 30x - 112
First, we distribute the 4:
4x + 4(56.5) = 30x - 112
Simplifying the expression:
4x + 226 = 30x - 112
Now we move all the x terms to one side and all the constants to the other:
226 + 112 = 30x - 4x
338 = 26x
Finally, we solve for x by dividing both sides by 26:
x = 13
Therefore, the solution to the equation 4(x+56.5)=30x-112 is x = 13.
Answer:
x=9.94
Step-by-step explanation:
4x + 226 = 30x - 112
226+112 = 34x
338 = 34x

Write the equation of the trigonometric graph. Use a positive coefficient on cosine for this activity.
The required equation of the trigonometric graph is y = 2cos[(π/8)(x-2)-2] which represents the cosine function.
What is the cosine function?The cosine function has a range of values between -1 and 1, and it is a periodic function that repeats every 2π radians or 360 degrees.
The graph of the cosine function is a wave-like curve that oscillates between -1 and 1, with a period of 2π radians or 360 degrees.
As we can see, the function's behavior repeats itself. In terms of the form of the function, we may select any interval of length 2π and the following interval of length 2π will be equal to the previous one.
Here, y = 2cos[(π/8)(x-2)-2]
Thus, the equation of the trigonometric graph is y = 2cos[(π/8)(x-2)-2] which represents the cosine function.

On a small town map, where each unit represents 2 miles, the football field is located at (1,−1), the elementary school is located at (1,2), the middle school is located at (−4,2), and the high school is located at (−4,−1). Which statement is true?
Answer: We can plot the given points on a coordinate plane where each unit represents 2 miles:
y
| E(1,2)
|
| M(-4,2)
|
|
|H(-4,-1) F(1,-1)
|___________________
x
Now we can see that the distance between the football field (F) and the high school (H) is 5 units in the x direction and 1 unit in the y direction, which corresponds to a distance of 5 x 2 = 10 miles in the x direction and 1 x 2 = 2 miles in the y direction. Using the Pythagorean theorem, we can find the distance between the two points:
distance = sqrt((10)^2 + (2)^2)
= sqrt(104)
So the distance between the football field and the high school is approximately 10.198 miles. Therefore, the statement that is true is:
"The distance between the football field and the high school is approximately 10.198 miles."

In an examination, Julius scored 5 more marks than John who in turn scored 4 marks less than Grace. If the total mark scored by the three students was 150. Find the mark of each student?
Making linear equations for given scores, Grace scored 51 marks, John scored 47 marks, and Julius scored 52 marks in the examination.
What is a linear equation, exactly?
A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a variable, with the degree of each variable being 1. In other words, a linear equation is an equation of a straight line, which can be expressed in the form of y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept of the line. Linear equations are used to model relationships between variables that have a constant rate of change, such as distance traveled over time or cost per item.
Now,
Let's assume that Grace's score is x.
Then, John's score will be x-4.
And, Julius's score will be x-4+5 = x+1.
The sum of their scores is given as 150. So, we can write an equation as:
x + (x-4) + (x+1) = 150
Simplifying the equation, we get:
3x - 3 = 150
Adding 3 to both sides, we get:
3x = 153
Dividing by 3 on both sides, we get:
x = 51
So, Grace's score is x = 51.
John's score is x-4 = 47.
And, Julius's score is x+1 = 52.
Therefore,
Grace scored 51 marks, John scored 47 marks, and Julius scored 52 marks in the examination.

How many more saplings with a height of 27 1/4 inches or less were there than saplings with a height greater than 27 1/4 inches?
(Total saplings- Saplings with a height greater than 27 1/4 inches) = Number of saplings with a height of 27 1/4 inches or less.
How to find height of an object?To find the height of an object in mathematics, you must first identify the shape of the object. Then, use the relevant formula for the shape to calculate the height. For example, if the object is a right triangle, the height can be found by using the Pythagorean Theorem. Additionally, if the object is a rectangle, you can use the formula for the area of a rectangle to calculate the height. Finally, if the object is a circle, you can use the formula for the circumference of a circle to find the height.
To solve this question, we will use the numerical approach. First, we need to subtract the number of saplings with a height greater than 27 1/4 inches from the total number of saplings. Then, we subtract the result from the total number of saplings. The result will be the number of saplings with a height of 27 1/4 inches or less.

A grocer wants to mix two kinds of coffee. One kind sells for $0.90
per pound, and the other sells for $2.40
per pound. He wants to mix a total of 28
pounds and sell it for $1.45
per pound. How many pounds of each kind should he use in the new mix? (Round off the answers to the nearest hundredth.)
In order to create a 28-pound blend that he can sell for $1.45 per pound, the grocer should combine approximately 17.73 pounds of the less costly coffee and 10.27 pounds of the more expensive coffee.
How many pounds of each kind should he use in the new mix?Let's designate the quantity of the less expensive coffee X and the more expensive coffee Y. Since we are aware that the grocer wishes to combine 28 pounds altogether, we can write:
x + y = 28
The total profit from selling the mixture would be: 28($1.45) = $40.60 because we also know that he intends to sell it for $1.45 per pound.
The costs and quantities of the two varieties of coffee can be used to create a new equation.
0.9x + 2.4y = $40.60
With two variables in each equation, we now have two equations that we can solve by substitution or elimination. Use of substitution
28 + y = x - 0.9x + 2.4y = 40.60
0.9x + 2.4(28 - x) = $40.60
0.9x + 67.2 - 2.4x = $40.60\s-1.5x = -$26.60\sx = 17.73
We can apply the first equation to determine y now that we know x: x + y = 28.
17.73 + y = 28 \sy = 10.27

What is your net pay, if you have Federal taxes taken out at 10%, State taxes at
4.5% and FICA at 6%?
4. If you make $20 an hour and you work 40 hours a week, You also worked 5 hours of overtime, at time and a half, what is your gross pay for the week?
5. What is your net pay, if you have Federal taxes taken out at 14%, State taxes at 4.5% and FICA at 6%?
Answer:
1. Gross pay = hourly rate x hours worked
Gross pay = $14 x 32 = $448
2. Net pay = gross pay - deductions
Federal taxes = 10% of gross pay = 0.1 x $448 = $44.80
State taxes = 4.5% of gross pay = 0.045 x $448 = $20.16
FICA = 6% of gross pay = 0.06 x $448 = $26.88
Total deductions = $44.80 + $20.16 + $26.88 = $91.84
Net pay = $448 - $91.84 = $356.16
3. Gross pay = hourly rate x hours worked
Gross pay = $17 x 40 = $680
4. Regular pay = hourly rate x hours worked
Regular pay = $20 x 40 = $800
Overtime pay = (hourly rate x 1.5) x overtime hours
Overtime pay = ($20 x 1.5) x 5 = $150
Gross pay = regular pay + overtime pay
Gross pay = $800 + $150 = $950
5. Net pay = gross pay - deductions
Federal taxes = 14% of gross pay = 0.14 x $950 = $133
State taxes = 4.5% of gross pay = 0.045 x $950 = $42.75
FICA = 6% of gross pay = 0.06 x $950 = $57
Total deductions = $133 + $42.75 + $57 = $232.75
Net pay = $950 - $232.75 = $717.25

Hello! 5/6 2/5 in simplest form
Answer:
Step-by-step explanation:
5/6 - 2/5 = 25/30 - 12/30 = 13/30
Answer:
Step-by-step explanation:
To subtract two fractions, we need a common denominator. The smallest number that 6 and 5 both divide into is 30.
Converting the fractions to have 30 as the denominator, we get:
5/6 = 25/30
2/5 = 12/30
Now we can subtract:
25/30 - 12/30 = 13/30
Therefore, 5/6 - 2/5 = 13/30 in simplest form.
A bookstore needs to sell at least 235 books. The number of books the store sells is described by 745-30b,where is the price per book.
Select the answer choice in each blank to make the statement true.
The range of the (profit per book)
Sold should be
(greater than $30 )
(between $0 and $17)
(greater than $17)
(between $17 and $30)
The parentheses are the choices for the answer.
The choice in the blank to make the statement true will be D. between $17 and $30)
How to explain the informationRevenue = Price per book × Number of books sold = (745 - 30P) b
Since the store needs to sell at least 235 books, we have:
Revenue ≥ 235 × Price per book = 235(745 - 30P)
Simplifying this inequality, we get:
745b - 30Pb ≥ 235 × 745
P ≤ (745/30) - (235/b)
Since we want to find the minimum profit per book sold, we need to maximize the value of (235/b). The maximum value of (235/b) occurs when b is minimized
If we assume that the cost per book is constant, then the profit per book sold will increase as the price per book increases. Therefore, we can say that the minimum profit per book sold that would enable the store to sell at least 235 books is greater than $17.
