Answer:
f-1(x) = x + 12.
Step-by-step explanation:
let y = x - 12
Now find x in terms of y:
x = y + 12
so the inverse is the following ( replace y by x):
f-1(x) = x + 12.

Answer:
(a) exactly two unique triangles
Step-by-step explanation:
The third angle is ...
180° -50° -80° = 50°
Two of the angles are the same, so two of the sides are the same length. The given side measure can be either one of the two unique side lengths, giving rise to exactly two unique triangles.
Answer:
x = -0.8
<CAD = -8
Step-by-step explanation:
10x + 4 = 5x - 4 (Clean up)
10x = -8 (Divide each side by 10)
x = -0.8
<CAD = 5x - 4
<CAD = 5(-0.8) - 4
<CAD = -4 - 4
<CAD = -8
The equation is more than that numbor
