Answer:
Alright well first off you start by converting everything to fractions, but decimals work better for me. So it would be 40.5 and 1.25, 40.5 being miles and the other gas. Divide 40.5 by 1.25, giving you 32.4
<u><em>His car get 32.4 miles per gallon</em></u>
Answer:
B)
Step-by-step explanation:
Given f(x) = ( 7 - 8x )²
let f(x) be y,
y = ( 7 - 8x )² .............to find inverse we have to make x the subject.
±√y = 7 - 8x
-8x = √y - 7
x = (±√y - 7 ) / -8
Then,
Inverse of ( 7 - 8x )² is 
and is a function.
Answer:
0
Step-by-step explanation:
There is no 7
<span>It will take Yanni 20 minutes to catch up with Tracy. This can be determined with the fact that average velocity equals change in distance divided by change in time. Rearrange the equation so that we are solving for the final time, then set Tracy's equation equal to Yanni's equation and solve for the final time.</span>
Answer:
Step-by-step explanation:
vertex-form equation for a vertical parabola with vertex (h,k):
y = a(x-h)² + k
y = -1.5(x+2)²
vertex (-2,0)
y-intercept = -1.5(0+2)² = -6
