You are using 0.05 gallons per mile of a SUV gas tank that holds 16 gallons. y = - 0.05x + 16. (Or, if you wish you may use
y = 16 - 0.05x. They are the same equation.) Use x-values: 0, 160, and 320.

So I know how to do this problem, but I was wondering if anyone could possibly help me with setting up the t-table? I'm not sure what numbers to use if I have start at 0 and go all the way up to 320.

Respuesta :

Here, we just use the following x values and put them into the equation.

y = - 0.05x + 16
y = -0.5(0) + 16
y = 16

y = - 0.05x + 16
y = -0.5(160) + 16
y = -80 + 16
y = -64

y = - 0.05x + 16
y = -0.5(320) + 16
y = - 160 + 16
y = -144

Now, to set up the table, you could list the x values and the y values. 

x values :- 0,160, 320
y values:- 16, -64, -144

Answer:

X y

0 16

160 8

320 0

Step-by-step explanation:

I chose to use y = 16 - 0.05x

The X Values are given to you so you have to use 0,160, and 320

Plug in the X and solve

X=0        Y=16-0

       Y=16

 

X=160 Y=16-(0.05)160

        Y=16-8

         Y=8

 

X=320 Y=16-(0.05)320

        Y=16-16

       Y=0
