Hopefully that helps I’m sry but I had to crop the image so it isn’t perfect
Answer:
8−4 a
Step-by-step explanation:
x=g(h(a−4))
h(a−4)=−2(a−4)−5 = −2 a+8−5=3−2 a
Apply g.
g(h(a−4))=g(3−2a)=2(3-2a)+2=6−4a+2
Answer: second option.
Step-by-step explanation:
In order to solve this exercise, it is necessary to remember the following properties of logarithms:

In this case you have the following inequality:

So you need to solve for the variable "x".
The steps to do it are below:
1. You need to apply
to both sides of the inequality:

2. Now you must apply the properties shown before:

3. Then, rounding to the nearest ten-thousandth, you get:

When you're looking to simplify a fraction, the best thing to do is to find a common factor between the two numbers.
In this case, 10 is a common factor, so therefore, divide both sides by 10.
30/10= 3
40/10= 4
Therefore, the fraction in its simplest form is 3/4
Hope this helps
