How do I solve this?

1 answer:

8 0

The product of the two segments from the two chords are equal.

4(4+5)=(x-2)(x-2+x+4) or 36=(x-2)(2x+2) or x^2-x-20=0 or (x-5)(x+4)=0

So x=5.

What is the slope of the line that passes through the points (12,-8) and (-9,-11)

Sauron [17]

Answer: 1/7

Explanation:

1. Use the formula, y2-y1/x2-x1
Plug in the points, (12, -8) and (-9, -11) into the formula.
Point (12, -8): 12 is the X1 and -8 is the y1.
Point (-9, -11): -9 is the X2 and -11 is the y2
So, -11--8/-9-12

2. -11--8/-9-12= -3/-21= 1/7
