The answer to the question is y = $4.25x
Answer:
So x=4 and y=-5 would work.
Step-by-step explanation:
When you multiply complex conjugates, you get a real result.
Example:

I replace
with -1 since
.
is a real number (there is no imaginary part, no i).
So what is the conjugate of 4+5i?
4-5i
So x=4 and y=-5 would work.
A multiple of the complex conjugate would work as well.




This is still a real number; there is no imaginary part,no i.
Charlotte's speed in meters per second is 2.5 meters per second.
What I did:
9 k per hour= (9/60)=per minute
9/60=0.15=15 m/m
0.15/60=0.025
0.025=2.5 m/s.
That is why Charlotte's speed in meters is 2.5 m/s.
Answer:

Step-by-step explanation:
Heart rate will be represented by
, minutes will be represented by
.
Here's the equation I came up with:

We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.

This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.
I hope this helps!
