I'm just going to give the answers snce so many questions
1. 2
2. 2/(m^2)
3. 1/(16x^8)
4. 3x^4
steps one: the one that starts with squareing both sides (√5x-9)^2=4^2)
23. x=9
24. 0
last graph one: third one (one that starts at 2 up from the origin)
Answer:

Step-by-step explanation:
In this question, we're going to solve the equation.
What we would do is plug in the given information in the right variable. In this case, we would plugin -8 to x, since x = -8
We are solving for y, so we would nee to find how much y = ?
Your equation should look like this:

Lets solve:

When you're done solving, you should get y = 2
This means that y = 2

Answer:x=3
Step-by-step explanation:3x+2=11
3x=11-2
3x=9
x=9/3
x=3
4(1/3) divided by 1(1/6) equals 26/7 or 3 and 5/7
Hope I didn't mess up for your sake.
