-18.5 = -2 (7f + 7.5)
-18.5 = -2×7f + (-2)×7.5
-18.5 = -14f + (-15)
-18.5 = -14f - 15
add 15 to both sides
-18.5 +15 = -14f - 15 + 15
-3.5 = -14f
f = -3.5/-14 = 0.25
Answer:
I think you have to muitly the number by the powers frist the subtract add add subtract
Step-by-step explanation:
Supplementary = equal to 180 degrees.
We can set up an equation.
2x + x = 180
Combine like-terms:
3x = 180
Divide both sides by 3 to isolate the x.
x = 60.
So one angle is 60 degrees and since the other one is twice of x, it is 120 degrees. If you add 120 and 60 degrees, you should get 180 degrees.
Nevertheless, the measures of the angles are 60 and 120 degrees.
Hope you could understand.

Answer:
m=-17/4
Step-by-step explanation:
Slope is equal to m= y-y/x-x
Therefore it will be 9-(-8)/-4-0
