Answer: 86 + 7.5 = 93.5
Step-by-step explanation:
Answer:
(x-1) is factor of our function.
Step-by-step explanation:
We are given a function
and we are asked to find the correct factor from the given options.
Let us factor out our polynomial.



Therefore, (x-1) is correct choice for factor of our polynomial.
Y=90x+2,000
90 is the rate of change because the hot air balloon descends 90 feet per minute.
And 2,000 is the starting point because the hot air balloon started the descent at 2,000 feet.
