Answer:
B. & E.
Step-by-step explanation:
First, to find your slope, put your line into slope-intercept form.


Your slope is
.
Now, you can find the y-intercept of your parallel line by plugging your given point and your slope into point-slope form.

Your y-intercept is 1.
If you notice, answer choice E is equivalent to one of our steps in converting it to point-slope form. Therefore, E is one of your answers.
The equation of your parallel line is:

B is also a correct answer.
If you put B into slope-intercept form, you get the following:

This, of course, is equivalent to the parallel line which we already found, so we know it is parallel.

Step-by-step explanation:
Velocity ratios are calculated by dividing the driver gear by the driven gear. The driver gear or pulley is the one connected to the power - e.g. the pedals on a bicycle or the motor. To calculate the speed of the driven gear - multiply the speed of the driver gear by the velocity ratio.
Answer:
Change: subtract old value from new value. Example: You had 5 books, but now have 7. The change is: 7−5 = 2. Percentage Change is all about comparing old to new values.
