researcher conducted a research and got the observations: 50, 60, 65, 75, 80, 85 and 90. Transform variable x into y. Establish the relation between x and y. (a) by multiplying it with a constant 6 and adding another constant 2 to it. (b) by dividing it with 5 and subtracting 3 to it.

The answer is : v = 55 + 8m plug in m = 25 v = 55 + 8(25) = 255 25 minutes after baxter begins filling the tank, the volume of water in the tank will be 255 gallons. slope: m = 8 gal/min for every min the water is on, the volume of water in the tank increases by 55 gallons. y-intercept: 55 (0,55) the initial volume of water in the tank was 55 gallons.
