*Sorry I messed up my math please read the new answer.
Use distrubitive property to get rid of parentheses. Multiply -3 by 4r and -8 to get -12r+24=36. Then zero out 24 by subtarcting 24 from both sides. You. should then have -12r=12. Divide by -12 on both sides to get r by itself. Your answer should be r=1*. Hope this helps :)

Answer:

Step-by-step explanation:
Given

The number line is missing from the question.
So, I will answer the question and also draw the number line to show the product.


To represent this on a number line;
We draw a number line of 15 points, and place a dot on the 6th point.
This represents 6/15

The formula for the Axis of symmetry is -b/2a. Which is -(-2)/2(1) = 2/2 = 1. The axis of symmetry is the X of the vertex, so just plug the 1 into the equation. So the Y= 0, so the vertex is (1 , 0)
