Answer:
See below in bold.
Step-by-step explanation:
f(x)=(x-15)(x+1)(x-10) = 0
The zeroes of the function are found as follows:
x - 15 = 0, so x = 15.
x + 1 = 0 and x - 10 = 0.
- in the same way -1 and 10 are also zeroes.
She used
cans of black paint.
Step-by-step explanation:
Given,
Number of cans of black paint = x
Number of cans of white paint = y
Given equation;
y=2x Eqn 1
Amanda used 5 cans of white paint, therefore,
y=5
Putting in Eqn 1
![5=2x\\2x=5](https://tex.z-dn.net/?f=5%3D2x%5C%5C2x%3D5)
Dividing both sides by 2
![\frac{2x}{2}=\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B5%7D%7B2%7D)
Writing in fraction form;
![x=2\frac{1}{2}](https://tex.z-dn.net/?f=x%3D2%5Cfrac%7B1%7D%7B2%7D)
She used
cans of black paint.

Answer:66666
Step-by-step explanation:
If the man works for $25 an hour ans spends $125 on materials he will have to make equal or more than what he spent
25x ≥ 125
then you divide 25 from each side and that will leave you with
x≥ 5
so this man need to work 5 or more hours to break even or make a profit.
