1. factor the following using the gcf: 10xy3 - 25x2y2 + 15xy
a. 5x(2y2 - 5xy2 + 3y)
b. 2x(5y3 - 12xy2 + 7y)
c. 5xy(2y2 - 5xy + 3)
2. solve by factoring the gcf: 16x2 - 4x = 0
a. {0, 4}
b. {0, 1/4}
c. {-1, 4}
d. {4, -4}

c is the correct answer

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
