r^2+7=45-r
i think this is the write answer, i havent done that kind of math in awhile.
N/-2 > 4 is same as N/-2 * -2 > 4* -2
So, N < -8 (N should be always less than -8)
The answer is the third one of y = 6x.
As you substitute x = 1, you get y = 6.
You substitute x = 2, you get y = 12.
B
the rest of them would not make sense plus you have to have brains
