Triangle xyz is reflected across the x-axis, and x = (-11, 8). What are the coordinates of x’

x'= (-11,-8)

Step-by-step explanation:

First, make a graph and plot point "x" (the rest of the points are unnecessary)

Next, count how many units (from point "x") it takes you to get to the x-axis (which is the horizontal line) The answer to that is 8

Then, from the point you ended on, count 8 down. You should get (-11,-8)

111

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
