Answer:
m perpendicular = 
Step-by-step explanation:
slope is 3
m = 3
the equation of a perpendicular line to y = 3x - 8 musts have a slope that is negative reciprocal of the original slope
A. An angle and its supplement equals 180∘ . So subtract 55∘ from 180∘ to get the supplemental angle.
B. The supplement of 170 degrees is 180-170 = 10 degrees. The complement of 55 is 90 - 55.
sorry i don't know the number to C, but i hope i helped a little <3
Answer:
(3,6)
Step-by-step explanation:
2x-3y = -12
x+y=9. Solve for either y or x
-x. -x
y = -x + 9. Substitute this for the y
2x-3(-x+9)= -12
2x +3x-27 = -12. Add like terms
5x -27 = -12
+27. +27. Inverse operations
5x = 15
÷5. ÷5
x = 3
x + y = 9
3 + y = 9. Substitute 3 for x
-3. -3. Inverse operations
y = 6
No solutions, since the lines are parallel and never meet. Hope I helped :)
