A 120-gallon tank that is initially full of water is drained at a rate of 6 gallons per minute. Explain how to write and graph a linear function that models the number of gallons of water left in the tank after x minutes. Use the coordinate plane below to graph the function. Show your work.

The linear function that models the number of gallons of water left in the tank is 120 - 6X = Y.

To determine a linear function that models the number of gallons of water left in the tank after X minutes, the following calculation must be performed:

120 - 6X = Y

So, for example, after 10 minutes, the equation would operate as follows:

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
