# Aremote-control airplane descends at a rate of four feet per second. after six seconds it is 116 feet above the ground. write the equation in point-slope form that models the situation. then find the height of the plane after eight seconds. y â€“ 116 = – 4(x â€“ 6) 108 feet y â€“ 6 = – 4(x â€“ 116) 438 feet y â€“ 4 = 116(x â€“ 6) 236 feet y â€“ 116 = – 6(x â€“ 4) 92 feet

After 3 seconds it’s been descending for 3 seconds at a rate of 2 feet per second. so it’s gone down 6 feet, and now it’s at a height of 67. so it started off at 73.

its height after x seconds is 73 – 2x. (73 to start off with, minus 2 feet per second that’s passed.)

after 8 seconds it will be at a height of 73 – 2*8 = 73 – 16 = 57.

The answer would be A. 1 1/5

48/40 = 1 8/40

1 8/40 Simplify to 1 1/5

Hope this helps!

I believe it is 60-10=x because it says she purchased it with 60$ but recieved 10$ in change causing the amount we dont know to be a variable such as “x”
