Answer:
c)5
Step-by-step explanation:
9x^2-2x+ 25 = 8x^2+8x
9x^2-2x+ 25 - 8x^2-8x = 0
x^2 - 10x + 25 = 0
c)5 ------> 5 * 5 - 10 *5 + 25 =25 - 50 + 25 = 50- 50 =0
The other two options are (x -5) or (x + 1).
The best way to go about finding this is by dividing. You can do this through synthetic division or by long division.
After dividing by x + 3, you'll be left with x^2 - 4x - 5, which can be factored. To factor, always check factors of the last number that add to the middle number. The factors of -5 are either 1 and -5 or 5 and -1. Since the first pair add to the middle coefficient, use those in the parenthesis.
In a function, each input (x-) value has exactly one output (y-) value. That's not the case here, where we have (-4,5) and (-4,3) (two different y-values for one x-value). Eliminating either (-4,5) or (-4,3) will make this relation into a function.

3,500×4×2/100= 280/100 = $2.80
Answer:
Step-by-step explanation:
100-10 : 100
90 : 100
504 : x
x=540x100/90
x=50400/90
x=560
