Answer:

option C (many)

Step-by-step explanation:

4(z-5)+2=4z-18

Distribute the numbers inside the parenthesis

4(z-5)+2=4z-18

4z-20+2=4z-18

Combine like terms

Subtract 4x from both sides

4z-20+2=4z-18

-20+2=-18

-18=-18

Both sides are equal. So there are more than one solution for x

Answer is option C (many)

f(g(x)) is a composite function:

f(g(x))=f(\sqrt{x+5})=2\sqrt{x+5}-1

Plug in <em>x</em> = 4:

f(g(4)) = 2\sqrt{4+5}-1=2\sqrt9-1=2\cdot3-1=\boxed{5}

so the answer is C.

How do I solve this equation: -5/6b + 3/4 = 1/2b - 2/3 ?
Gre4nikov [31]
First get like things on the same side:
-5/6b - 1/2b= -2/3 - 3/4

Then find equivalent fractions to make the equation easier to solve.
-5/6b - 3/6b= -8/12 - 9/12

Then just add things together and solve.
-8/6b= -17/12
-8b= 6(-17/12)
-8b= -17/2
b= (-17/2)/-8
b= 17/16

You can then plug the answer back into the original question to make sure it is the correct answer.
