Answer:

C

Step-by-step explanation:

3(3 + x) = 15 + x

Open bracket

9 + 3x = 15 + x

Collecting like terms

3x - x = 15 - 9

2x = 6

Dividing by 2

x = 6/2

x = 3

Answer: x=39

3x-15=2x+24
-2x -2x
1x-15=24
+15 +15
x=39

Explanation: Non-consecutive angles are congruent. Set the two angles equal to each other and solve for x. You should get x=39.

Step-by-step explanation:

Slope of the line through (0,3) and (2,5) = (5-3)/(2-0) = 1.

Equation of line: y = x+3

Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below. parabolic func
storchak [24]

Answer:

0

Step-by-step explanation:

The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:

Already with the figure we can solve the question.

We have that the average exchange rate in this case would only take the normal slope between those 2 lines

. Furthermore we know that the slope (m) is given by:

m = (y2-y1) / (x2 - x1)

From the graph we have to:

y2 = 0

y1 = 0

x2 = 5

x1 = 3

we replace:

m = (0-0) / (5 - 3)

m = 0

Therefore the average rate is 0.
