Answer:
Step-by-step explanation:
The average rate of change can be found by using the following formula
Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.
By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.
Now that we know this, we can simply plug these values into the formula!
Good luck!
Answer:
Step-by-step explanation:
Given the expression:
First, we open the outer brackets
Therefore:
Since the angle under angle 3 is a right angle (because of the little orange square) we can assume that angle 3 plus angle 2 equals 90 degrees. so
(2x - 5) + (4x - 13) = 90
6x - 18 = 90
6x = 108
x = 18
measure of angle 2 = 36 - 5 = 31
measure of angle 3 = 72-13 = 59

In case the user wants to see workings. These problems can easily be solved on a calculator, but can we work them out in our heads? ;)
9.34-3.029
=9.340-3.029
=9.340-3.000-0.029
=6.340-0.029
=6.311
