Are these supplementary, complementary, or neither? 1.
m∠ 1 = 62 degrees m∠ 2 = 128 degrees

2.
m∠ 3 = 44 degrees m∠ 4 = 46 degrees

If you steal answers or just answer to get point, I will report you.

Neither, complementary

Step-by-step explanation:

1. 62 + 128 = 190 (Neither)

1. 44 + 46 = 90 (Complementary)

Adding up to 90 is complementary, adding up to 180 is supplementary

the answer is a

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
