Its 2x +20
hope this helped you
Well first you do 7+5 to equal 12, and then you multiply 12 by 6 and get 72, then you add the 3 to get 75. 6(7+5)+3=75. Hope this helps!!
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following equation:

So we have to:
The slope is:
The cut-off point with the y axis is:
Answer:
The slope is: 
The cut-off point with the y axis is: 
10% of 24$ is 2,4$
24$-2,4$ is 21,6$
21,6$>20$
