This does not make sense, but with the logic, it would be B. Please comment to clarify so I can make changes if needed.
ANSWER: B
We have that
y=-2x+3
y=(1/3)x-4
using a graph tool
see the attached figure
the solution of the system is the point (3,-3)
We are given the following functions:
![\begin{gathered} f(x)=7\sqrt[]{x}+6 \\ g(x)=x+6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%3D7%5Csqrt%5B%5D%7Bx%7D%2B6%20%5C%5C%20g%28x%29%3Dx%2B6%20%5Cend%7Bgathered%7D)
We are asked to determine the composite function:

The composition of functions is equivalent to:

Therefore, we replace the value of "x" in function "f" for the function "g", therefore, we get:
![(f\circ g)(x)=f(g(x))=7\sqrt[]{x+6}+6](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%28x%29%3Df%28g%28x%29%29%3D7%5Csqrt%5B%5D%7Bx%2B6%7D%2B6)
Since we can't simplify any further this is the composition.
Now we are asked to determine the domain of this function. Since we have a square root, the domain must be the values of "x" where the term inside the radical is greater or equal to zero, therefore, we have:

Now we solve for "x" by subtracting 6 from both sides:

Therefore, the domain is:
Hello, so the equation for the area of a trapezoid is A = (a+b)*(h/2)
In which, a is one of the bases, b is the other base, and h is the height. A is the Area. If you wanna solve for height, rearrange the equation to what h equals.
First divide (a+b) from both sides
A/(a+b) = h/2
Now multiply 2 on both sides
2(A/(a+b)) = h
Now you have it rearranged equal to just h. Plug in the values now.
2(3.9/(4+2.5)) = h
2(3.9/(6.5)) = h
2(.6) = h
1.2 = h
