What does (x^2 - 3x + 1) + (2x^2 + 5x + 7) equal?

3x^2+2x+8

Step-by-step explanation:

1. x^2+2x^2=3x^2

2. -3x+5x=2x

3.1+7=8

3x^2+2x+8

Step-by-step explanation:

You just add the values if it were subtraction then you would distribute the negative.

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.
