We see that AB bisects PQ, forming the two angles we are given. These two added together is equal to 180 (because they are supplementary angles, which add up to 180 degrees).
<u>So, add them together, set it to 180, and solve for x.</u>
6 + 2x + 4 = 180
<u>Combine like terms.</u>
10 + 2x = 180
<u>Subtract 10 from both sides from the equation.</u>
2x = 170
<u>Divide by 2 on both sides of the equation.</u>
x = 85 <- This is the answer.
For the following problems, since we know that point P is bisecting the segments, it means that it is splitting the segment in half, creating two equal parts. This means that all we have to do is set the two segments equal to each other.

2x + 3 = x + 7
<u>Subtract 3 and subtract x from both sides of the equation.</u>
x = 4 <- This is the answer.
21.
4x + 3 = 8x - 11
<u>Add 11 and subtract 4x to and from both sides of the equation.</u>
14 = 4x
<u>Divide by 4 from both sides of the equation.</u>
x = < - This is the answer.
22.
7x - 3 = 5x + 2
<u>Subtract 5x from both sides of the equation and add 3 to both sides of the equation.</u>
2x = 5
<u>Divide both sides by 2.</u>
x = <- This is the answer.

You get the answer by inserting values in slope formula and then solving for k. I'll call k, y_2
So the answer k = -5 is incorrect because k = 11.
Hope this helps.
Answer:
Step-by-step explanation:
Factor it by first setting it equal to 0:
Now subtract 9 from both sides:
Divide both sides by 4:
Then take the square root of both sides:
x = ± , which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,
x = ± is an equivalent radicand, we can now replace -1 with its imaginary counterpart:
x = ±
Each one of the elements in the radicand are perfect squares, so we simplify as follows:
x = ±
And there you go!
