Answer:
Choice D
Step-by-step explanation:
First we should find the slope of the equation, so since it's perpendicular to the other equation that means it's the opposite and the reciprocal of that slope. So the slope is .
Now we have to find the y-intercept. We already know the x-intercept, so we could use that to find the y-intercept. For that we need to know the slope and one ordered pair, which is (36,0). Then we plug into this formula .
So now that we found the y-intercept we just have to put it all together....
In every case the larger number is rounded up to 2E13.
Divide this by 3E8:
2E13 = 200000E8
-------- --------------- is approx equal to 70000 (dollars).
3E8 3E8
Answer:
y =3
Step-by-step explanation:
Slope of zero means it is a horizontal line
Horizontal lines are of the form
y =
The y coordinate is 3 so
y =3
