A traffic helicopter descends 154 meters to be 313 meters above the ground. What was the original height of the helicopter? Let h be the original height of the helicopter. What is a subtraction equation that models the problem?

H= 347m + 182m

H = 529 m

so the original height of the helicopter is 529 meters

Step-by-step explanation:

467 feet off the ground

Step-by-step explanation:

If the helicopter descends 154 meters, this means the helicopters height drops 154 meters from its original height. If the helicopters current elevation is 313 meters, to find its original height, we can inverse the equation. So instead of subtraction, use addition. 154+313=467 meters is the original elevation.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

5+2x=a
