Answer:
Perpendicular line y = (- 8/3)x - 76/3.
Parallel line y = (3/8)x - 1
Step-by-step explanation:
y = 3/8
x + 3
1) Perpendicular line has negative reciprocal slope.
m = - 8/3
y = (- 8/3)x + b
Point (-8, - 4)
- 4 = (- 8/3)*(-8) + b
-4 - 64/3 = b
b = - 76/3
y = (- 8/3)x - 76/3
2) Parallel line has the same slope.
m = 3/8
y = (3/8)x + b
Point (-8, -4)
- 4 = (3/8)*(- 8) + b
- 4 + 3 = b
b = - 1
y = (3/8)x - 1
Answer:
0
Step-by-step explanation:
The slope is 1/0, and that equals 0.
Answer:
13/3

<span>The formula is area of trapezoid = average base x average height
We're going to do this in reverse.
Area = 80.75
[(7 + 12)/2] = 9.5 (height)
height = 80.75 / 9.5 = 8.5
The height is 8.5, so the answer is D.</span>
Y = 2x^2 - 4x + 2
y = 2(x^2 - 2x + 1)
2(x - 1)^2 = = 0
so the graph will just touch the x axis at x = 1
So there is one zero duplicity 2.
