Answer:
40 and 50,20 and 70
Step-by-step explanation:
complementary angles are angles that added equal to an angle of 90 degrees and it says they are not congruent so the two angles are diferent
Answer:
-250
Step-by-step explanation:
![- 2(5)^{ \frac{(9)}{3} } \\ - 2(5)^{3} \\ - 2(125) \\ - 250](https://tex.z-dn.net/?f=%20-%202%285%29%5E%7B%20%5Cfrac%7B%289%29%7D%7B3%7D%20%7D%20%20%5C%5C%20%20-%202%285%29%5E%7B3%7D%20%5C%5C%20%20-%202%28125%29%20%5C%5C%20%20-%20250)
hope that makes sense
Answer:
(-2,6)
Step-by-step explanation:
The solution to the system of equations should be true for both equations. This means that if you substitute -2 into both equations, you should get 6 as the y value for both equations.
They gave you a graph, and to find the solution from the graph, you just look at which point is shared by both lines, or at which point both lines intersect.
There is also a mathematical way to do it using substitution and elimination, but you should master the graphing method first before moving onto those.
