At time x = 0, water begins to drip steadily out of a water tank. After 1 hour, there are 5.6 gallons of water in the tank. After 7 hours, 3.2 gallons remain. Write a linear function rule that models the number of gallons of water y left in the tank for any number of hours x.

f(x) = -.4x + 6

explanation:

Simply find the slope using the formula

The b value can be found by substituting a point and then isolating b, the point i used was (1, 5.6) because that was the closest point to the start of the graph

Thank me later :)

(or just give brainliest)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

answer: 72: 111
