Aplane descends to 5/6 of its cruising altitude, a. what is the new altitude? write an algebraic expression! i really need ! will mark 50

Your answer would be y=5/6x + a

The reason why this is the answer is because 5/6 is the amount you're decreasing (your slope). A would represent where you start off at before you descend.

idk

step-by-step explanation:

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.
