Supplementary angles have a sum of 180 degrees.
If one angle is x, its supplementary angle is 180-x.
We are told that x is 8 less than triple its supplements so:
x=3(180-x)-8
x=540-3x-8
4x=532
x=133
Answer:
The answer to your question is below
Step-by-step explanation:
Inequality 1
7(x + 2) - 8 ≥ 13
7x + 14 - 8 ≥ 13
7x + 6 ≥ 13
7x ≥ 13 - 6
7x ≥ 7
x ≥ 7/7
x ≥ 1
Inequality 2
8x - 3 < 4x - 3
8x - 4x < - 3 + 3
4x < 0
x < 0 / 4
x < 0

Answer:
-3
Step-by-step explanation:
y = -3x + b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b
y = -3x - 16
Answer:
(x+6) (x-3)
Step-by-step explanation:
Set the difference first.
_x_= -18
_+_ = 3
6 x -3 = -18
6+(-3)= 3
Now distribute it with the x^2
(x+6) (x-3)
Tada!
