Do elimination
2x + y = 3
x - y = 3
Add these
3x = 6
X = 2
Plug in 2 for x
4(2) + 2y = 6
8 + 2y = 6
2y = -2
X = 2, y = -1
Answer:
C
Step-by-step explanation:
"at most" meaning less than or equal to
Answer:
Depends on how the X and Y values are oriented but if the X value is on the bottom and the Y is on the top, then the graph is decreasing

Have a great day!
Answer:
A = 47° and B = 43°
Step-by-step explanation:
Express angle A in terms of angle B, that is
A = B + 4
Complementary angles sum to 90°, hence
A + B = 90, that is
B + 4 + B = 90
2B + 4 = 90 ( subtract 4 from both sides )
2B = 86 ( divide both sides by 2 )
B = 43
Hence
∠B = 43° and ∠A = B + 4 = 43 + 4 = 47°
