Factor the expression.

grigory [225]

Hey!

First, let's write the problem,
$4r^2-64$
Factor out the common term, which is 4,
$=4\left(r^2-16\right)$
Then, let's factor this part: $r^2-16$
We are going to factor it using the difference of squares rule.
$=\left(r+4\right)\left(r-4\right)$
Our final factored answer would be,
$=4\left(r+4\right)\left(r-4\right)$

Thanks!

What is the intersection of y=7 and y=1\2x+6

kotegsom [21]

Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7

and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so

to find the intersection, yo just find when both sentances are correct so

y=7
subsitute that into y=1/2x+6

7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x

so the point (2,7) is the intersection
