Answer:
y = 2x + 2
Explanation:
We can use the following equation to write an equation in slope-intercept form.
[tex]y-y_1=m(x-x_1)[/tex]Where (x1, y1) is a point in the line and m is the slope. Additionally, the slope can be calculated as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x2, y2) is another point in the line.
So, replacing (x1, y1) by (0, 2) and (x2, y2) by (3, 8), we get that the slope is equal to:
[tex]m=\frac{8-2}{3-0}=\frac{6}{3}=2[/tex]Finally, replacing m by 2 and (x1, y1) by (0, 2), we get:
[tex]\begin{gathered} y-2=2(x-0) \\ y-2=2x \\ y-2+2=2x+2 \\ y=2x+2 \end{gathered}[/tex]Therefore, the equation in slope-intercept form is:
y = 2x + 2
Alexis found that a bushel of apples contain 78 large apples she separated the Apple into three groups such that second group had twice as many as the first and the third group has six more than the first how many apples are in each group
Answers
So we know that are three groups, and the second one had twice of apples that the first one, and the third group has six more than the first, so we have nine parts of the amount of the first group separated in the three groups, to have the 78 apples separated in all the groups we are going to need that the first group contain 78/9 apples, the second one contain 2*(78/9) = 156/9 apples and the third one contain 6*(78/9) = 468/9 apples.
So the answer is the first group contain 78/9 apples, the second one contain 2*(78/9) = 156/9 apples and the third one contain 6*(78/9) = 468/9 apples.

Find the value of x.
Answers
Answer:
x = 5
Step-by-step explanation:
Hey, sure thing! (: All of the angles in this triangle are equal, which means that this is an equilateral triangle, and since this is an equilateral triangle, then that means all sides must be equal to each other.
Now, let's set up an equation to show that.
2x + 11 = 6x - 9
+ 9 + 9
2x + 20 = 6x
- 2x -2x
20 = 4x
4 4
x = 5
Tada! That's how we got the answer. Best of luck with the rest of your responsiblities! <3
Answer:
x = 5
Step-by-step explanation:
equilateral triangle definition:
a triangle whose all three sides are of equal length and 3 congruent angles of 60°
so
2x + 11 = 6x - 9
2x - 6x = - 9 - 11
- 4x = -20
x = - 20 : (-4)
x = 5
------------------------------
check (remember pemdas)
2 * 5 + 11 = 6 * 5 - 9
10 + 11 = 30 - 9
21 = 21

Find the rule for the line that passes through each of these pairs of points. Use : y - y1 = m(x - x1).
(4, -8) and (0,4)
(3,1) and (-3, -1)
Answers
The rule for the line that passes through the points (4, -8) and (0, 4) is 3x + y = 4
The rule for the line that passes through the points (3, 1) and (-3, -1) is x - 3y = 0
Equation of a line and rule for a lineFrom the question, we are to determine the rule for the line that passes through each of the given pairs of points
For (4, -8) and (0, 4)
First, we will determine the slope, m, of the line
Using the formula,
m = (y₂ - y₁)/(x₂ - x₁)
m = (4 - (-8))/(0 - 4)
m = (4 + 8)/-4
m = 12/-4
m = -3
Now, for the rule
Using the formula,
y - y₁ = m(x - x₁)
Then,
y - (-8) = -3(x - 4)
y + 8 = -3x + 12
3x + y = 12 - 8
3x + y = 4
The rule is 3x + y = 4
For (3, 1) and (-3, -1)
The slope, m is
m = (-1 - 1)/(-3 - 3)
m = -2/-6
m = 1/3
Now, for the rule
Using the formula, y - y₁ = m(x - x₁)
y - 1 = 1/3(x - 3)
3(y - 1) = x - 3
3y - 3 = x - 3
-3 + 3 = x - 3y
0 = x - 3y
x - 3y = 0
Hence, the rule is x - 3y = 0

Explanation:
Let the original price of the item = p dollars.
If there is an 18% markup, the new price of the item will be:
[tex]\begin{gathered} \text{New Price}=p+(18\%\text{ of p)} \\ =p+(\frac{18}{100}\times p) \\ =p+0.18p \\ =1.18p \end{gathered}[/tex]Yes, the price of the item with an 18% markup is the same as multiplying the original price by 1.18.

Given that, the original price of an item is p dollars.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the original price of the item = p dollars.
If there is an 18% markup, the new price of the item will be
New price = p + 18% of p
= p + 0.18p
= 1.18p
Yes, the price of the item with an 18% markup is the same as multiplying the original price by 1.18.

What is defined as the tangent?A tangent is a line drawn out of an external point that passes through a point on a curve in geometry. Tangents are common in everyday life; for example, when riding a bicycle, each point on the circumference of a wheel forms a tangent with the road.For the given question;
As 16 unit line is tangent on the circle, thus it makes 90 degrees angle with the radius of the circle.

After doing some mathematical operations, the value of A is 3.465.
What are mathematical operations?An operation, also known as an "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the operations that are most frequently studied.So, A = π(R² - r²):
Where π = 22/7, R = 7/4 and r = 7/5.Now, solve the expression as follows:
A = π(R² - r²)A = 22/7((7/4)² - (7/5)²)A = 22/7(49/16 - 49/25)A = (22/7 × 49/16) - (22/7 × 49/25)A = (11 × 7/8) - (22 × 7/25)A = 77/8 - 154/25A = [25(77) - 8(154)]/200A = [1925 - 1232]/200A = 693/200A = 3.465Therefore, after doing some mathematical operations, the value of A is 3.465.

(a)
the cost function is
C(x) = 300 + 20x
(b)
the revenue function is
R(x) = 35x
(e)
the profit function
P(x) = R(x) - C(x) = 35x - 300 - 20x = 15x - 300
(d)
break-even is the point where C(x) and R(x) are equal :
C(x) = R(x)

therefore, the product should not be produced at all.
Part 1 of 2 Question content area top Part 1 Two of the most expensive cars in the world are car A and car B. The prices of these two cars differ by more than $. The price of car A is $. a. Assuming that you do not know which model is more expensive, write an absolute value inequality that describes this situation. Use x for the price of car B. b. What are the possibilities for the price of car B?
Answers
Considering the given situation, it is found that:
a. The absolute value inequality is: |x - 131745| > 15000.
b. The possibilities for the price of car B are of x < $116,745 or x > x > $146,745.
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.|x| = -x, x < 0.It gives the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.
In this problem, the difference between the price of car B of x and the price of car A of $131,745 is greater than $15,000, hence the absolute value inequality that models this situation is:
|x - 131745| > 15000.
Hence the possibilities for the price of car B are:
x - 131745 < -15000 -> x < -15000 + 131745 -> x < $116,745.x - 131745 > 15000 -> x > 131745 + 15000 -> x > $146,745.What is the missing information?The complete problem is given by:

292,000 after several years decrease by 8%
Answers
After several years of an 8% decrease, the house's value is $268,640 currently.
What is a percentage decrease?In this situation, the percentage decrease refers to the fractional devaluation of the property value.
We can compute the percentage decrease by directly determining the amount (absolute value in dollars) of the decrease or by indirectly determining the value after the decrease, using mathematical operations.
The initial value of the house = $292,000
The percentage decrease in value = 8%
The Decrease Value = $23,360 ($292,000 x 8%)
The Current Value of the house = $268,640 ($292,000 - $23,360) or {$292,000 x (1 - 8%)}
Thus, the house decreased by $23,360 or 8% and is currently worth $268,640.
