Answer:
B -4/5
Step-by-step explanation:
The slope of line D is given by
m = (y2-y1)/(x2-x1)
= (6-1)/ (5-1)
=5/4
We want the slope of the line perpendicular
That would be the negative reciprocal
- (4/5)
Answer:
38%
Step-by-step explanation:
set up proportions
114 x
----- = -------
300 100
cross multiply
11400 = 300x
divide
x= 38
It was reflected vertically then flipped
Answer:
<h2> The first</h2>
Step-by-step explanation:
That means every x wich is greater than 7
Answer:
A ( -2 , 9 )
Step-by-step explanation:
<u>Idea:</u> You find the first derivative of f(x), and then set it equal to the desired slope. You'll find some x. That we will use to find the point.
f'(x) = 3x^2 + 12x + 20
f'(x) = 8
3x^2 + 12x + 20 = 8
3x^2 + 12x + 12 = 0
3 ( x^2 + 4x + 4 ) = 0
3 ( x + 2 )^2 = 0
x + 2 = 0
x = -2
So, the desired point is:
A ( -2, f(-2) ) --> A ( -2 , 9 )
