What is -8-2r=-7v-7v+16
Mariulka [41]

Answer:

r=7v−12

Step-by-step explanation:

Let's solve for r.

−8−2r=−7v−7v+16

Step 1: Add 8 to both sides.

−2r−8+8=−14v+16+8

−2r=−14v+24

Step 2: Divide both sides by -2.

−2r

−2

=

−14v+24

−2

r=7v−12

The table shows the distance a cyclist rides her bicycle over time. Is the rate of change in distance with respect to time const
Vinil7 [7]

From the relationship between the distance and time, the rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

<h3>What is a linear equation?</h3>

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the distance travelled by the bike after x minutes.

From the table:

Rate of change = (4480 - 1120) / (4 - 1) = 1120 ft/min

The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
