Answer:

Step-by-step explanation:
We are given the function:

And we want to find k⁻¹(-4).
Recall that by the definition of inverse functions:

Let k⁻¹(-4) = <em>x, </em>where <em>x</em> is an unknown value. Then by definition, k(x) must equal -4.
So:

Solve for <em>x: </em>

Hence, k(-39/5) = -4. By definition of inverse functions, then, k⁻¹(-4) = -39/5.
Answer:
B
Step-by-step explanation:
come on really
The perimeter of the shape shown is 63 units
For a trapezoid, the area is:
S=(b+B)h/2, where b and B are the bases, and h is the height.
b=2
B=2+2+2=6
h=2.
S=(2+6)×2/2=8
You need to find the prime factors of each term in order to find the greatest common factor.
The answer is 3.
