Answer:
The equation is 18h=378
h=21
Step-by-step explanation:
So first you have to set up the equation
so if she makes 18 dollars an hour the first part of the equation would be 18h
She made 378 dollars in one week so now the equation is 18h=378
The answer is h=21 because 378/18 is 21
Answer:
Option D. − 8/5
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
we have the points
(−1, 7) and (4, −1)
substitute in the formula
![m=\frac{-1-7}{4-(-1)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-7%7D%7B4-%28-1%29%7D)
![m=\frac{-1-7}{4+1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-7%7D%7B4%2B1%7D)
![m=\frac{-8}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-8%7D%7B5%7D)
![m=-\frac{8}{5}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B8%7D%7B5%7D)
B) 1 and the square root of 3

Let x represent a 2-point basket, and y represent a 3-point basket.
Basket equation: x + y = 16
Point equation 2x + 3y = 39
Solve using system of equations:
if x + y = 16, then x = 16 - y
Plug into the second equation:
2(16-y) + 3y = 39
32 - 2y + 3y = 39
32 + y = 39
y = 7
So the number of 3-point baskets scored was 7. Hope this helps, let me know if there’s a step you don’t understand! :)
