F(x)= 0.02x^2 + 0.08x + 30.6
so for f(0) all that means is where you see x plug 0 for x..
f(0)= 0.02(0)^2+ 0.08(0) + 30.6
f(0)= 30.6
f(4)= 0.02(4)^2 + 0.08(4) + 30.6
f(10)= 0.02(10)^2 + 0.08(10) + 30.6
attached are calculated answers
Answer:
All that's necessary is to add 4 to both sides of the equation. This gives
... y = 1/2(x -8) +4
If you like, you can simplify this by eliminating the parentheses and collecting terms.
... y = 1/2·x -4 +4
... y = (1/2)x

Answer:</h3>
c. 150 miles
<h3>
Step-by-step explanation:</h3>
You want to find the number of miles (m) that make the charges equal.
... 40 +0.25m = 25 + 0.35m
... 15 = 0.10 m . . . . . . add -25-0.25m
... 150 = m . . . . . . . . . divide by the coefficient of m
For 150 miles, the rental cost will be the same for both companies.
