Answer:
slope = -7/3
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1)
We need to implement the points into this formula
y2 = 3
y1 = -4
x2 = -1
x1 = 2
(3-(-4)) divided by (-1-2) = 7/-3 = -7/3
The cost per paint brush is $4 if the Nevaeh pays a total of $24
for two sets of paint brushes, and each set costs the same amount of money and contains three paint brushes.
<h3>What is a fraction?</h3>
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
Nevaeh pays a total of $24 for two sets of paint brushes. Each set costs the same amount of money and contains three paint brushes.
The cost for each set = 24/2 = $12
In each sets of paint brushes there are total of 3 brushes which cost $12
So, each brush cost = 12/3 = $4
Thus, the cost per paint brush is $4 if the Nevaeh pays a total of $24
for two sets of paint brushes, and each set costs the same amount of money and contains three paint brushes.

Answer:
The correct answer is: Option D: 8
Step-by-step explanation:
Given that she spent $208 on the sewing machines
And
the equation for profits to break even is:
208 + 10x = 36x
In order to find the number of purses to break even, we have to find the value of x
So,
![208+10x=36x](https://tex.z-dn.net/?f=208%2B10x%3D36x)
Subtracting 10x from both sides
![208+10x-10x = 36x-10x\\208 = 26x](https://tex.z-dn.net/?f=208%2B10x-10x%20%3D%2036x-10x%5C%5C208%20%3D%2026x)
Dividing both sides by 26
![\frac{208}{26} = \frac{26x}{26}\\x = 8](https://tex.z-dn.net/?f=%5Cfrac%7B208%7D%7B26%7D%20%3D%20%5Cfrac%7B26x%7D%7B26%7D%5C%5Cx%20%3D%208)
The number of purses is 8
Hence,
The correct answer is: Option D: 8
