Answer:

The cost of 30 gallons of gas is $74.7.

Step-by-step explanation:

  • Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.
  • The cost 24 gallons is $59.76 to him.
  • Now we need to find the cost of 30 gallons.
  • To solve this problem use a direct variation formula.
  • Solve for constant variation.

Step 1 of 3

Here we need to find the cost of 30  gallons.

Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.

The cost of 24  gallons is $59.76  to him.

Let, x  be the number of gallons and y  be the cost or price for gas.

Use the formula for direct variation which is given by y=kx.

Step 2 of 3

Now substitute the value y=$59.76 and x=24.

Put value in y=kx, we get

$$\begin{aligned}&59.76=k \times 24 \\&k=2.49\end{aligned}$$

Substitute value of k is y=kx, we get y=2.49x

Step 3 of 3

Now we need to find the value of y that is the cost for 30 gallons.

Again use direct variation formula y=kx and value of k and x, we get $y=2.49 \times 30$

$$y=74.7$$

How to tell if its identifying functions is <br> a function or not
Svetach [21]

Answer:

Step-by-step explanation:

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.
