What is the answer to 3(2x+5)=3x+4x

6x+15=3x+4x

6x+15=7x

15=7x-6x

15=1x

x=15/1

x=15

3(30+5)=45+60

3(30+5)=105

45+60=105

so x=15

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.

answer: 12

step-by-step explanation:

because yes
