Answer:
First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)
That is the first error of Alan.
Now, there is another error.
If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).
But we can not really divide by zero, so we should state that:
m can not be zero, if a line is horizontal, the perpendicular line must be vertical.
Answer:
The inverse function is 
Step-by-step explanation:
The given function is
.
This function is only invertible on the interval,
.
To find the inverse on this interval, we interchange
and
.

We now make
the subject to get,



But the given interval is
, This implies that,
.

<h3>Answer: 32%</h3>

Explanation:
There are 10 cards total. Of which, 8 are not blue. You can think of it as "there are 2 blue, so 10-2 = 8 are not blue", or you can count out the non-blue cards. The first option is faster in my opinion.
The probability of not getting blue is 8/10 = 0.80
After picking a first card and then putting it back, we will still have 10 cards. There are 4 pink cards out of this total, so 4/10 = 0.40 is the probability of getting a pink card.
--------
Multiply the two values we found earlier
0.80 * 0.40 = 0.32 = 32/100 = 32%
Answer: Franklin could end at 4 different points.
Step-by-step explanation:
Given: Franklin the fly starts at the point (0,0) in the coordinate plane.
At each point, Franklin takes a step to the right, left, up, or down.
i.e. there are 4 choices of directions [A coordinate plan has 4 quadrants]
If he moves 10 steps, then the number of different points Franklin could end up at = choices of directions
= 4
Hence, Franklin could end at 4 different points.
Answer:
C is (-18, 24)
Scale factor --> 1 1/3
A is (9, - 4 1/2) *4 1/2 is also 4.5
