2 because you make them with the same denominators that both go into each other EX: 8x9=72 7/8 now equals 63/72 and 4/9 now equals 28/72 now add them together 63/72 + 28/72= 91/72= 1 19/72
<u>Answer:</u>
143°
option c is correct!
<u>Explanation:</u>
Given:
Two angles are supplementary:
One angle = 37°
We know if two angles are supplementary their sum is equal to 180°.
Let another angle be x°
= > 37° + x° = 180
= > x° = 143°
Therefore another angle is 143°.
Answer:
280
Step-by-step explanation:
The average rate of change over the interval [-9, -3] is

That is, it's the ratio between the change in the function value over the length of the interval. Judging by the plot, we have <em>f</em> (-9) = 6 and <em>f</em> (-3) = -3. So the average rate of change is
