Answer:

Step-by-step explanation:

Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.

f(x) = 40 - 2x

For x = 0,

f(x) = 40 miles

For f(x) = 0,

0 = 40 - 2x

x = 20 minutes

This shows that helicopter traveled 40 miles in 20 minutes.

Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.

For x = 0,

f(x) = 500 miles

For f(x) = 0,

x = 100 minutes

Commercial jet traveled 500 miles in 100 minutes.

The rectangle ABCD is reflected across the y-axis. What are the<br> coordinates of the vertex A'?
Anit [1.1K]
The answer would be (-2,5), this is because when we reflect on the Y axis the Y stays the same and X changes and vise versa for the X axis. Then the amount of units away from the y axis is the amount of units more that it’s going to travel. Hope this helps
