Step-by-step explanation:
A
x + 3y = 5
(x, y) = (2,1)
x + 3y = 5
2 + 3(1) = 5
2 + 3 = 5
5 = 5
The equation is true
B.
y = –x + 3
(x, y) = (2, 1)
y = –x + 3
1 = -2 + 3
1 = 1
The equation is true
The answer is 87
(6x7) = 42
(5x9) = 45
42 + 45 = 87
A (42 degrees) bc the angles are across from each other so they’re equal
