The solution to this inequality is 4 < x or x > 4.
In order to solve this, follow the steps to solving an equation with one variable. The steps are below for you.
2x + 8 < 5x - 4 ------> Subtract 2x from both sides
8 < 3x - 4 -----> Add 4 to both sides
12 < 3x -----> Divide both sides by 3
4 < x
You need to show us the circle in order to let us answer the question.
27: C 28: B 29. A
And I kindly decline the marriage offer lol. If you need an explanation of how I did this then I will gladly do so they are pretty simple.
For the first one, x=-1, y=-8
Observe the given figure.
Here, angle T and R are the inscribed angles.
And sum of inscribed angles is half of measure of intercepted arcs.
Since, the measure of intercepted arcs is 360 degrees.
Therefore, 

Hence, the sum of the two angles is 180 degrees.
Therefore, these are the supplementary angles.
Therefore, angle T and angle R are supplementary angles.
Hence, proved.
