If (x − 6) is a factor of the polynomial function f(x) = 5x2 − 28x − 12, which of the following is another factor?
(5x − 2)
(5x + 2)
(2x − 5)
(2x + 5)

(5x + 2)

Step-by-step explanation:

The product of (ax + b) and (cx + d) is:

(ax + b) (cx + d) = ac x² + (ad + bc) x + bd

The leading coefficient is the product of the coefficients of each factor.

The constant is the product of the constants of each factor.

So if (x − 6) is a factor of 5x² − 28x − 12, the other factor must have a coefficient of 5 and a constant of 2.

(5x + 2)

found it xd it ok yt

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
