Reflection over the y-axis:
(x, y) ⇒ (-x, y)
Reflection of that over the line y = x:
(-x, y) ⇒ (y, -x)
Rotation counterclockwise by 270°:
(x, y) ⇒ (y, -x) . . . . . . equivalent to reflection over y, then over y=x.
The appropriate choice is ...
C) Reflecting over the y-axis and then reflecting over the line y = x.
At least $73.50 for 7x3 is 21 gallons and 10.50x7 is $73.50
4.25 + 2.25 +4x <= 9
combine like terms
6.5 + 4x< =9
subtract 6.5 from each side
4x< = 2.5
divide by 4
x< =2.5/4
x<=.625
