Answer: Choice B) 6 cm</h3>
==========================
Explanation:
Triangle PQC is congruent to triangle RQC. We can prove this through use of the hypotenuse leg theorem (HL theorem). Note that PC = RC are congruent radii, and also note that CQ = CQ through the reflexive theorem. We have a pair of hypotenuses and a pair of legs for the right triangles.
Then through CPCTC (corresponding parts of congruent triangles are congruent), we know that the pieces PQ and QR are congruent. For now, let's just call them x. They must add to PR which is 12, so,
PQ + QR = PR ..... segment addition postulate
x + x = 12
2x = 12
x = 6 ..... divide both sides by 2
QR = 6
This shows that if you have a radius perpendicular to a chord of a circle, then the radius will bisect this chord. Bisect means to cut in half.

Answer:
<h2>Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.</h2>

Answer:
{y,x} = {-6,-2}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 2x - 2
// Plug this in for variable y in equation [1]
[1] (2x-2) - x = -4
[1] x = -2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = 2x-2
x = -2
// Use the x value to solve for y
y = 2(-2)-2 = -6
