Answer: D. 7
Step-by-step explanation:
The problem tells you that x = 0 so replace everything that is x in the equation with 0 so the problem becomes
7 + (-3(0)^2)
Now we just solve the problem normally.
solve the problem in the parenthesis first, we must multiply -3 times 0^2 is 0
so now our problem is 7 + 0 which is 7

Answer:
For mileages higher than 80 miles Company A will charge less than Company B
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
Company A charges $111 and allows unlimited mileage.
Company A =111
Company B has an initial fee of $55 and charges an additional $0.70 for every mile driven
Company B = 55+0.70m
Where m is the number of miles.
Company A has to charge less than Company B
a<b
111 < 55+0.70m
Solving for m
111-55 < 0.70 m
56 < 0.70m
56/0.70 < m
80 < m
For mileages higher than 80 miles Company A will charge less than Company B
