After traveling for 4 hours and 18000 miles ,an airplane begins a steady descent when it begins descending its altitude(height) is 33,000 feet . After 8 mins it is at 17,000 feet write a function that models the planes altitude

i dont know

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
