A. When solving results in an inequality that is true, such as 7 > 3, the solution of the inequality is

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

a - base

b - exponent

so,

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
