Because Point Slope Form contains m, or slope, in itself, look at the number that is multiplying the parentheses.
-5/4 is m, or slope.
Answer:

Step-by-step explanation:
∠E = 1/2 (mCD - mAB)
<u>Where mCD = 110° and mAB = 30°</u>
∠E = 1/2 (110° - 30°)
∠E = 1/2 (80°)
∠E = 40°

Answer:

Step-by-step explanation:
The focus of the parabola is (0,9)
and the directrix is y=-9.
The equation of this parabola is given by:

The vertex of this parabola is at the origin.
The value of p is the distance from the vertex to the focus.
p=9-0=9
The equation of the parabola is


Or

There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
