F(x) = x² - 8x + 5
f(-1) = (-1)² - 8*(-1) + 5
= 1 + 8 + 5 = 14
f(-1) = 14.
Answer:
x=13
Step-by-step explanation:
18-5=13. You have to subtract 5 from 5 itself and then 18.
450
If he used 1/3 of the stock bottle, then you have
150=1/3x
Now, you multiply both sides by 3, which gives you
450=x
So, originally there were 450 bottles in the stock bottle
