Answer:
Step-by-step explanation:
I translated it into:
60+10x=15x
(x= the amount of months btw)
take 10x from each side
60=5x
divide each side by 5
x=12
one year until the cost of the two is the same.
Answer:
108.7 ft
Step-by-step explanation:
Put 30 where x is and do the arithmetic.
y = -3.29·30 -10 = -98.7 -10 = -108.7
The trend line predicts the depth to be 108.7 ft after 30 minutes.

<em>Comment on this problem</em>
Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
Answer:
Slope = -9/2
Two points are (-2,9) and (2,-9)
Step-by-step explanation:
The two points the equation should go through are (-2,9) and (2,-9), (Dark Green and Light Blue).
The slope-intercept is calculated using the two points above;
-9 - 9 = -18
2 - (-2) = 4
Slope = -18/4 or -9/2
Hope this helps!
