Y = -3x + 13
Steps and the graph are on paper
Is it multiple choice? Other wise, the variable "d" would be $63, and the variable "h" would be the 6 hours she babysat. Your equation would look something like this:
$63 = 9.5(6)
The next step would look like the following:
$63 = $57
The statement would be false. It is not true, considering that 63 is not equal to 57.
Answer:
true
Step-by-step explanation:
given
=
( cross- multiply )
4x = 40 ( divide both sides by 4)
x = 10
Answer:
n = -8
Step-by-step explanation:
![- 5n - 2 = 38](https://tex.z-dn.net/?f=-%205n%20-%202%20%3D%2038)
Collect like terms and simplify
![-5n = 38+2\\\\-5n = 40](https://tex.z-dn.net/?f=-5n%20%3D%2038%2B2%5C%5C%5C%5C-5n%20%3D%2040)
Divide both sides of the equation by -5
![\frac{-5n}{-5n} = \frac{40}{-5}](https://tex.z-dn.net/?f=%5Cfrac%7B-5n%7D%7B-5n%7D%20%3D%20%5Cfrac%7B40%7D%7B-5%7D)
Simplify
![n = -8](https://tex.z-dn.net/?f=n%20%3D%20-8)
Answer: 9 x 10^-2
Step-by-step explanation: you need to get the number between 1-9. You can do that by moving the decimal to the right 2 times. That gives you 9.00 or 9. Since you moved it to the right 2 times that means the exponent would be negative
