We try the all of the numbers until we find it
1*1=1
2*2=4
3*3=9
4*4=16
5*5=25
6*6=36
7*7=49
So the answer is 7
B) -23 because a double negative is a positive so it’s -35 + 12 which is -23
We have that
x------------------> <span>represent the number of hours Steven babysits
y----------------- > </span><span>represent the amount he charges
for x=6 hours
y=</span><span>$37.50 ----------------> y/x=37.5/6=6.25
</span>for x=8 hours
y=$50---------------------> y/x=50/8=6.25
therefore
y=6.25x
the answer is
y=6.25x
