Answer:
y = 6x
Step-by-step explanation:
To write an equation, find the unit rate or constant of proportionality (k).
Using a point on the line, (3, 18):
Constant of proportionality, k = y/x = 18/3
k = 6
To write an equation, substitute k = 6 into y = kx.
Thus:
y = 6x
3/5 of 42000 is 25200 so the amount of people who did not vote is 16800 because the beginning amount of 42000 subtracted from 25200 gives you the final answer
If that's confusing the answer is 16800 votes didn't pick the winner
The equation to solve this should be x+3x=60

y=cos(2x)
<span>dy/dx=-2sin(2x) </span>
<span>dy/dx at the point x=pi/4 is </span>
<span>dy/dx=-2sin(2*pi/4) </span>
<span>dy/dx=-2 sin(pi/2) </span>
<span>dy/dx=-2 </span>
<span>therefore the slope of the tangent is -2
</span>
using this slope find the equation of the line
<span>(y-y')=m(x-x') </span>
<span>(y-0)=-2(x-pi/4) </span>
<span>y=-2(x-pi/4)</span>
I believe the answer is: C. (2,-1)
I hope this helps!
