X³ - 9x² + 5x - 45
x²(x - 9) - 5(x - 9) ⇒ x³ - 9x² - 5x + 45 INCORRECT
x²(x + 9) - 5(x + 9) ⇒ x³ + 9x² - 5x - 45 INCORRECT
x(x² + 5) - 9(x² + 5) ⇒ x³ + 5x - 9x² - 45 CORRECT
It just needs to be rearranged.
x(x² - 5) - 9(x² - 5) ⇒ x³ - 5x - 9x² + 45 INCORRECT
Answer: the answer is A)
Step-by-step explanation:
Since the rugs have to be made in LESS THAN 240 hours, that automatically cancels out C) and D). Then you just have to plug in the number of small rugs into X and the number of medium rugs into Y.
Any value of x must be less than -5 for n to be negative. (x<-5)
F(x)=(-1)^2+3
f(x)=1+3
f(x)=4
The slope is 0 because 4 is a constant.
