Tell whether the angles are complementary, supplementary or neither m^3=27, m^4=63

Complementary.

Step-by-step explanation:

27+63=90 so the pair of angles is complementary.

Complementary angles is a pair of angles that add up to 90.

Supplementary angles is a pair of angles that add up to 180.

the discriminant is 64 + 4*1*12 = 112

this is prime.

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
