Answer:
C. (2, 5)
Step-by-step explanation:
Looking at the answer choices, you can see that solving for y will tell you which choice is correct. We can eliminate x from the equations by adding 4 times the second equation to the first:
(8x -3y) +4(-2x +3y) = (1) +4(11) . . . . . adding the equations to eliminate x
9y = 45 . . . simplified; next we divide by 9
y = 5 . . . . . matches choice C
_____
Check
8(2) -3(5) = 16 -15 = 1
-2(2) +3(5) = -4 +15 = 11 . . . . the answer checks OK in both equations
Answer:
55
Step-by-step explanation:

Step-by-step explanation:
Answer:
Complementary, X = 60 degrees
Step-by-step explanation:
Complementary = 90 degree angle
Supplementary = 180 degree angle
(x - 30) + x = 90
(60 - 30) + 60 = 90
30 + 60 = 90
