Distribute the 2 to get the pink box
10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4
Answer:
6
Step-by-step explanation:
In y = Asin(Bx + C) +D,
|A| is the amplitude
Amplitude: |-6| = 6
Answer:
Congruent angles are two or more angles that have the same measure. In simple words, they have the same number of degrees. It's important to note that the length of the angles' edges or the direction of the angles has no effect on their congruency. As long as their measure is equal, the angles are considered congruent.

Answer:
JL = 9√13
Step-by-step explanation:
All of the triangles in this geometry are similar:
∆MKL ~ ∆MLJ ~ ∆LKJ
Corresponding sides of similar triangles are proportional, so you can write the relations ...
JL/JM = JK/JL ⇒ JL² = JM·JK
LM/JM = KM/LM ⇒ LM² = JM·KM
Using the second expression to find JM, we have ...
JM = LM²/KM = 18²/12 = 27
We know that JK = JM +KM. Then the first expression can be ...
JL² = 27·(27 +12) = 9²·13
JL = 9√13
