Answer:
(-3,-4)
Step-by-step explanation:
When reflecting across the y-axis, you will mirror the coordinates across the y-axis. This means (5,-4) will turn into (-5,-4) because mirroring it across the y-axis will only change the x coordinate. Then, to translate it to the right, you move to the right two times to give you (-3,-4). The y-coordinate will never change in this situation because you are only reflecting and moving left and right.
Let's solve your equation step-by-step.

Answer:
c=5
Use ratio and proportion:
$29.50 is to 250 ft. as how much is to 40 ft.
29.5 / 250 = x / 40
x = 40(29.5) / 250
x = 1180 / 250
x = 4.72
40 ft. would cost $4.72
