Answer: THIRD OPTION.
Step-by-step explanation:
Given the following inequality:

You can follow these steps in order to solve it:
1. Apply Distributive property on the left side:

2. Add 15 to both sides of the inequality:

3. Finally, divide both sides of the inequality by 3:

The symbol is
means "Greater than or equal to", and indicates that 7 is include in the solution.
Therefore, the solution can be expressed as:
Now you must mark this point with a closed dot on the number line and shade everything to the right.
I don't understand what one
There would be three rows, going to the right. Each row, would be 15 high.
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
