Answer:
24%
Step-by-step explanation:
45 + 37 + 52 + 94 + 72 = 300
72/300 = 0.24 x 100
= 24%
First, you would create an equation for this problem.

=

Next, you would cross multiply.
15x = 1,800
Now, you would isolate the x. To do this, you would divide both sides by 15.
x =
120It is a 120% increase. I hope this helps!
Answer:
A -4 ≤ x ≤ -2
Step-by-step explanation:
The graph is constant where there is a flat, horizontal line. The graph is flat in the interval -4 ≤ x ≤ -2. This is where the graph will be constant. In all of the other parts of the graph, the y-values are changing. Since the line is flat, the y-value doesn't change.
