A helicopter is hovering at an altitude of 1,450 Feet above see level. It descends at a constant rate of 75 feet per minute. Which function can be used to determine its height, H, after m, minutes?

what is all that apply?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

i believe a. 12x≥120 is the answer
