B) 0.56
becouse you only need to divide 5 by 9
I believe the answer is 1/x-4
This is because the x-5 on the numerator and denominator cancel out
The image is (6,3) after a reflection over the y-axis
Things we know:
Six total pots = # of 10" + # of 8"
$78 total = cost of 10" + cost of 8"
So:
6 = x +y
and
78 = x*(cost of x) + y * (cost of y)
78 = x*12 + y*15
We need:
x+y=6 AND 12x+15y=78
So our answer can only be B.
