Suppose you want to determine the number of miles you can drive in your car. your car gets 20 miles per gallon. the number of miles traveled varies directly with the number of gallons of gas the tank holds. write a direct variation equation that represents the situation. let y be the dependent variable and let x be the independent variable

y = 20x

Step-by-step explanation:

We know that the car gets 20 miles per gallon and the number of miles traveled varies directly with the number of gallons of gas the tank holds.

We are to write a direct variation equation which represents this situation.

Direct variation is expressed in the form , where is the constant of variation.

So for this situation, the direct variation equation will be:

Step-by-step explanation:

By  definition, a direct variation equation has the form shown below:

Where k is a constant, y is the dependent variable and x is the independent variable.

According to the problem, you know that your car gets 20 miles per gallon. The number of miles traveled varies directly with the number of gallons of gas the tank holds.

Then, you can write the following direct variation equation that represents the situation:

y: The number of miles traveled

x:  the number of gallons of gas the tank holds.

k: 20 (Because your car gets 20 miles/gallon)

Then:

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
