Therefore , the solution of the given problem of inequality graph comes out to be the graph of the inequality 2x - y ≤ -3 is a line that cuts through the x-y plane
What do you mean by inequality graph?An inequality graph is a graph that represents the solution set of an inequality, showing the values of the independent variable (usually represented on the x-axis) for which the inequality is true.
Here,
An inequality can be represented graphically by shading the region on a coordinate plane that satisfies the inequality. The direction of shading (above or below the line) depends on the inequality symbol.
The graph of the inequality 2x - y ≤ -3 in the x-y plane can be plotted by finding the boundary line for the inequality and shading the region that satisfies the inequality. To do this, we can start by setting the equation 2x - y = -3 and finding the x- and y-coordinates of the points on the line. Then we can plot these points and draw the line that connects them.
Next, we will determine which side of the line represents the solution set. To do this, we can pick a point that is not on the line and substitute its x- and y-coordinates into the inequality. If the inequality is true for the point, we shade the region that contains the point. If the inequality is false, we shade the region that does not contain the point.
So the graph of the inequality 2x - y ≤ -3 is a line that cuts through the x-y plane and is shaded on one side. The shaded region represents all the x- and y-coordinates that satisfy the inequality.

The flooring will cost $2 per square foot. How much would it cost Suzie to lay this flooring so it fully covers the floor of room?
Answer:
To find out how much it would cost Suzie to lay the flooring so it fully covers the floor of room, you need to know the area of the room's floor and the cost per square foot of the flooring.
If the flooring will cost $2 per square foot, and if the area of the room's floor is x square feet. Then the total cost will be $2x.
Without knowing the area of the room's floor, it is impossible to determine the cost of the flooring.
The lengths of the four sides of a quadrilateral (in feet) are consecutive integers. If the perimeter is
86
86 feet, find the value of the longest of the four side lengths.
Answer:
23
Step-by-step explanation:
because consecutive integers, that means each one is longer than the previous one
length 1= x
length 2 = x+1
length 3 = x+2
length 4 = x+3
so 4x+6 =86
x = 20

whats the sum of
1/2 and 1/14 pleaseee
Answer:
0.571428571
Step-by-step explanation:
To find the sum of two fractions with different denominators, a common denominator must be found.
In this case, the two in the denominator must be multiplied to make it 14.
14/2 = 7, so multiply 2 by 7 to get 14, and what you do to the bottom you must do to the top, so 1 * 7 = 7.
Now, your two fractions are 7/14 and 1/14. Add the numerators as the denominators are equal.
7+1 = 8
8/14 is the sum, which can be divided by 2 on the top and bottom to simplify.
8/2 = 4, and 14/2 = 7

Answer: so yea its the first one. im not that sure im just like saying what I know
Step-by-step explanation:
Estimate the area between the x-axis and the curve y = 2x' +1 on the interval (0, 2). Be sure to draw the correct picture for each approximation 5) Use a left hand approximation. a) Use 4 boxes b) Use 8 boxes
Using a left-hand approximation means that we will use the left endpoint of each interval to approximate the area under the curve.
a) Using 4 boxes:
The interval from 0 to 2 can be divided into 4 equal parts, so each part has a length of 0.5.
The height of each box will be the value of y at the left endpoint of each interval.
The area of each box can be calculated as follows:
For the first box, the left endpoint is (0, 1) and the height is 2(0) + 1 = 1. The area is 0.5 * 1 = 0.5.
For the second box, the left endpoint is (0.5, 2) and the height is 2(0.5) + 1 = 2.5. The area is 0.5 * 2.5 = 1.25.
For the third box, the left endpoint is (1, 3) and the height is 2(1) + 1 = 3. The area is 0.5 * 3 = 1.5.
For the fourth box, the left endpoint is (1.5, 4) and the height is 2(1.5) + 1 = 4.5. The area is 0.5 * 4.5 = 2.25.
The total area is the sum of the areas of all the boxes, so the total area is 0.5 + 1.25 + 1.5 + 2.25 = 5.
b) Using 8 boxes:
The interval from 0 to 2 can be divided into 8 equal parts, so each part has a length of 0.25.
The height of each box will be the value of y at the left endpoint of each interval.
The area of each box can be calculated as follows:
For the first box, the left endpoint is (0, 1) and the height is 2(0) + 1 = 1. The area is 0.25 * 1 = 0.25.
For the second box, the left endpoint is (0.25, 2.5) and the height is 2(0.25) + 1 = 2.5. The area is 0.25 * 2.5 = 0.625.
For the third box, the left endpoint is (0.5, 3) and the height is 2(0.5) + 1 = 3. The area is 0.25 * 3 = 0.75.
And so on, for all 8 boxes.
The total area is the sum of the areas of all the boxes, so the total area is 0.25 + 0.625 + 0.75 + ... + 3.375 = 5.125.
So, the area between the x-axis and the curve y = 2x + 1 on the interval (0, 2) can be approximated as 5 or 5.125 depending on the number of boxes used.

Brad is putting up a circular flower garden with a radius of 4.5 feet in his yard. He
will put plastic edging along the flowerbed. How many feet of edging will Brad need
to enclose his flower garden?
According to the problem Brad will need 28.27 feet of edging to enclose his flower garden.
What is edging?Edging in math is a technique that involves finding the maximum or minimum value of a function. It is typically used to optimize or increase the performance of a particular solution. In other words, edging is a process by which a function is “reduced” to its most efficient form. For example, a function that is non-linear can be “edged” to become more linear, thereby increasing its efficiency. Additionally, edging can be used to identify certain features within a solution, such as local maximums or minimums. Edging is an important tool in math, and it can be used in a variety of different applications, from optimization to data analysis.
Brad will need 28.27 feet of edging to enclose his flower garden. This is because the circumference of a circle is equal to 2πr, where r is the radius. Therefore, the circumference of Brad's flower garden with a radius of 4.5 feet is 28.27 feet.

The measure of angle t is (d) 103 degrees
How to determine the measure of angle tFrom the question, we have the following parameters that can be used in our computation:
The triangle
Using the law of cosines, we have the following equation:
t² = x² + y² - 2xy * cos(T)
Substitute the known values in the above equation, so, we have the following representation
44² = 32² + 24² - 2 * 24 * 32 * cos(T)
Evaluate the products and exponents
1936 = 1600 - 1536 * cos(T)
So, we have
cos(T) = -336/1536
Divide
cos(T) = -0.21875
Take the arccos of both sides
T = 103

Step-by-step explanation:
The y-intercept of a function can be found by looking at the point where the x-coordinate is 0. In this case, the y-intercept of the function is -3, as the point (0,-3) is on the graph.
The slope of a function can be found by looking at the change in y divided by the change in x between two points on the graph. In this case, we can use the points (0,-3) and (1,-1) to find the slope. The change in y is -1 - (-3) = 2 and the change in x is 1 - 0 = 1. So the slope is 2/1 = 2.
Therefore, the equation of the function can be written in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept. So the equation of the function is:
y = 2x - 3

Mother Money Bags has d dollar bills in her wallet. She splits the bills equally between her five kids, then gives each of them 3 more dollars in
change. If each child gets a total of $14, how many dollar bills did
Mother have in her wallet?
Answer:
Let's call the original number of dollar bills Mother had "d". Each child received d/5 + 3 dollars.
Since each child received $14, we have:
d/5 + 3 = 14
Multiplying both sides by 5, we get:
d + 15 = 70
Subtracting 15 from both sides, we get:
d = 55
So, Mother had 55 dollar bills in her wallet.

What are the laws of sines?The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law.
The side or unknown angle of an oblique triangle is found using the law of sine. Any triangle that is not a right triangle is referred to as an oblique triangle.
Given ΔTUV
t = 820 inches
∠U = 132°
∠V = 25°
and ∠T = 180 - 132 - 25
∠T = 23°
so according to the law of sines
[tex]\frac{SinT}{t} = \frac{SinU}{u}= \frac{SinV}{v}[/tex]
so u = t*(SinU/SinT)
u = 820(Sin132/sin23)
u = 820(1.9019)
u = 1559.58 inches = 1560 inches (approx)

Step-by-step explanation:
115 its rhe reuth i rhibk lol
Answer:
To find the cost of a hot dog and hamburger, we can set up a system of equations based on the information given. For example, let x be the cost of a hot dog and y be the cost of a hamburger. Then we have:
4x + 7y = 68 (equation 1)
7x + 3y = 67 (equation 2)
We can use substitution or elimination methods to solve the system of equations.
Substitution method:
Solve equation 1 for y in terms of x: y = (68 - 4x)/7
Substitute this expression into equation 2: 7x + 3((68 - 4x)/7) = 67
Simplifying and solving for x: 7x + 3(68 - 4x)/7 = 67
7x + 204 - 12x = 469
-5x = -401
x = 80
Substitute x = 80 back into equation 1: 4(80) + 7y = 68
320 + 7y = 68
7y = -252
y = -36
Therefore, the cost of a hot dog is $80, and the price of a hamburger is $-36 (which is not possible, it could be a typo or mistake in the given information)

F(x)=0.25x-2;H(x)=-F(x)
The solution to the function's operation of h(x) is -0.25x + 2.
What is a function?A function connects an element x to an element f(x) also known as (y) in another set. The domain of a function refers to the x-values and the range of the function is the set of values of f(x) i.e. (the y-values) that are produced by the values in the domain of the function, which is the set of values of x.
Given that:
f(x) = 0.25x - 2
h(x) -f(x)
We are going to simply replace the value of f(x) with h(x), i.e.
h(x) = -(0.25x - 2)
h(x) = -0.25x + 2
Therefore, we can conclude that the solution to the function's operation of h(x) is -0.25x + 2.
