You need to take the whole function of g(x) and plug it into every single x within f(x). Bit tricky, so it just means we need to be careful. Alright, so this is the first set-up<span><span><span><span>−2x−7</span><span>x−1</span></span>−7</span><span><span><span>−2x−7</span><span>x−1</span></span>+2</span></span>So what You should do is make the top portion and the bottom portion all into one fraction. This means I need a common denominator. So to do this, I'll take x-1 as a common denominator and multiply it up into the numerator and the imaginary 1 denominator of -7 and 2. Doing this I have:<span><span><span>−2x−7−7(x−1)</span><span>x−1</span></span><span><span>−2x−7+2(x−1)</span><span>x−1</span></span></span>From here if I divide the top fraction and the bottom fraction, (x-1) will cancel out dueto me flipping the bottom fraction and multiplying. So that leaves me with:<span><span>−2x−7−7(x−1)</span><span>−2x−7+2(x−1)</span></span>Now if I multiply everything out and combine like terms I will have:<span><span><span>−2x−7−7x+7</span><span>−2x−7+2x−2</span></span>=<span><span>−9x</span><span>−9</span></span>=x</span>So that is the first part. We have to check both ways to confirm they are actually inverses of each other, though. Take a look at this part and see if you can make sense of what I did.

Answer:
The answer is "
".
Step-by-step explanation:
Given value:
4 40 32
Solution:
If we divide the value by 4 it will give 10 and 8.
If we add the boxed value it will be equal to 72 and divide the value by 4 it will give a value 18.
Answer:
0.5x−7.8
Step-by-step explanation:
Let's simplify step-by-step.
0.5x−4−(1.5+2.3)
Distribute the Negative Sign:
=0.5x−4+−1(1.5+2.3)
=0.5x+−4+(−1)(1.5)+(−1)(2.3)
=0.5x+−4+−1.5+−2.3
Combine Like Terms:
=0.5x+−4+−1.5+−2.3
=(0.5x)+(−4+−1.5+−2.3)
=0.5x+−7.8
