A Tara has $800 in a bank account. that she uses to make automatic payments of her $101.51 monthly cable bill. IF Tara stops making deposits to that account, when would automatic payments make the value of the account zero?

answer: x=60

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

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.
