We are going to Multiply 9 by

.

, so your answer is
Answer:
false
Step-by-step explanation:
The solution is (2, -4).
We can solve this with the elimination method. Multiply the first equation by -2 and then add the two equations.
-20x + -12y = 8
20x + 10y = 0 Add the two equations
-2y = 8
y = -4
Now, just input -4 for y into either equation, you will get 2 for x.
Since A and B are the midpoints of ML and NP, we can say that AB is parallel to MN and LP. In order to find ∠PQN, we can work with the triangles PQB and NQB. According to SAS (Side-Angle-Side) principle, these triangles are congruent. BQ is a common side for these triangles and NB=BP and the angle between those sides is 90°, i.e, ∠NBQ=∠PBQ=90°. After finding that these triangles are equal, we can say that ∠BNQ is 45°. From here, we easily find <span>∠PQN. It is 180 - (</span>∠QNP + ∠NPQ) = 180 - 90 = 90°
