Answer:
40° and 140° (with x = -10)
Step-by-step explanation:
Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180

Answer:
C
Step-by-step explanation:
You can see from the graph that everytime x goes up by 1, y goes down by 4, so the slope is -4.
The y-intercept is at -1
This means that the equation would be C. y = -4x - 1
Hey There!
The answer to you're question is C, because squared means to the power of two. So, 39 * 39 is 1,521.

No because if you convert them into a percentage, you get 11/15 as 73.3% and 1/2 is 50%. Hope this helps
