In a race, a bicyclist travels 3/4 of a mile in 1/4 hour. Determine the unit rate for the speed in miles per hour.
5/2 miles per hour
(3/4÷1/4)=3 miles per hour☆☆☆☆☆☆☆
41/4 miles per hour
4 miles per hour
Answer:
34-5x
Step-by-step explanation:
(12+2x-9)-(-15+7x-16)
(3+2x)-(-31+7x)
3+2x+31-7x
34-5x

Divide both side by
and rearrange terms to get a linear ODE;

Multiply both sides by
:

The left side can be condensed as the derivative of a product:

Integrate both sides, then solve for
:

The lines are perpendicular because the slopes are negative reciprocals of eachother.
46.55= 47
48.09=48
44.475=44
45..238=45
49.601=50
47.7=48
