Atraffic helicopter descends 123 meters to be 309 meters above the ground, as illustrated in the diagram to the right. write an equation to describe the situation using h as the original height of the helicopter. what was the original height of the helicopter?
write an equation to describe the situation using h as the original height of the helicopter.

the original height of the helicopter=432 meters ;  h-123=309

Step-by-step explanation:

the original height of the helicopter = h       [Given]

now,

helicopter descends 123 meters

so, h-123

to be 309 meters above the ground

so, h-123=309

=>h=309+123

=>h=432

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

2x^2+5x+17
