Answer:
4
Step-by-step explanation:
He can make 10 more bowls of clay if he wants<span />
F(x) = x^2 - 3x - 7
f(-3) = (-3)^ 2 - 3(-3) - 7
f(-3) = 9 + 9 - 7
f(-3) = 18 - 7
f(-3) = 11
We know there are 4 quarts in a gallon, so how many quarts in 2.5 gallons anyway?
11.424242
isolate the repeating part
11+0.424242
focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242
subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
![x=\frac{42}{99}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B42%7D%7B99%7D)
so
