In order to check a solution, just plug in the coordinates. The 1 is x, and the -1 is the y. Just plug the numbers in and see if it works out:
y = 3x + 2
(-1) = 3(1) + 2
-1 = 5
-1 is NOT equal to 5, so (1, -1) is NOT a solution of y = 3x + 2.
2(12y) = 24y
(4y+6)(4y+6)= 8y+12
24y+8y+12
D. 32y + 12
If your choices are the following:
m∠V = 30°, m∠U = 60°, m∠W = 90°
m∠V = 90°, m∠U = 60°, m∠W = 30°
m∠V = 30°, m∠U = 90°, m∠W = 60°
m∠V = 60°, m∠U = 90°, m∠W = 30°
Then the answer is m∠V = 60°, m∠U = 90°, m∠W = 30°.
