Answer:
1st Graph
Step-by-step explanation:
Step 1: Find the inverse
y = 2x - 2
x = 2y - 2
x + 2 = 2y
y = (x + 2)/2
Step 2: Graph the inverse
Simply use a graphing calculator and we should see our answer is the top left graph.
159.2/3.2=49.75
take 159.2 and divide it by 3.2 and you get 49.75
to check your answer you would take 159.2 divided by 49.75
159.2 divided by 49.75 = 3.2
3.2 is 49.75 percent of 159.2
