Which of the following is a value of r for which (r + 2)(r − 3) = 0?

r = -2 or r = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

r2−r−6=0

Step 2: Factor left side of the equation.

(r+2)(r−3)=0

Step 3: Set factors equal to 0.

r + 2 = 0 or r − 3 =0

r = −2 or r = 3

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.

1/800 is the right answer
