Answer:

r=-7

Step-by-step explanation:

4r+12=-16

Subtract 12 from both sides.

4r=-28

Divide both sides by 4.

r=-7

Check our work with substitution:

4\cdot-7+12=-28+12=\boxed{-16}

We see that our work is correct.

<h3>4r + 12 = −16</h3>

<em>Subtract 12 from both sides.</em>

<h3>4r = −16 − 12</h3>

<em>Subtract 12 from −16 to get −28.</em>

<h3>4r = −28</h3>

<em>Divide both sides by 4.</em>

<h3>r = -28/4</h3>

<em>Divide −28 by 4 to get −7.</em>

<h3>r = −7 ==> Answer</h3>

Helen [10]

Answer:

-0.25 ; 120 seconds 72 seconds

Step-by-step explanation:

Dive rate is constant :

Change in elevation after 8 seconds :

18 feets to 20 feets below

Rate of change = distance / time

(18 - 20) feets / 8 seconds

(-2 / 8) = - 0.25 feets per second

To reach 50.feets :

She needs to cover (50 - 20) = 30 feets

Time = distance / speed ; 30 feets / 0.25 = 120 seconds
