Let's say you're renting a boat

Let h = number of hours you rent the boat

if it costs $46 per hour to rent a boat, then it will cost a total of 46*h or 46h dollars
Now let's say that you get a discount if you are a member. The membership fee is $86 leading to the discount hourly cost to be $25 per hour. If you rent for h hours, then you pay a total of 86+25h dollars

Writing 46h > 86+25h will represent cases when the nonmembership option is more expensive (and the membership option more cheaper). Solving for h will help determine when the membership option is cheaper.

6. If two quantities vary directly, which must be true of a graph showing the relationship between them?
larisa86 [58]

Answer:

The points of the graph form a straight line, and the line must pass

through the origin ⇒ answer d

Step-by-step explanation:

* Lets explain the meaning of vary directly

- Direct variation is a relationship between two variables

- Two variable quantities have a constant ratio

- One of them equal the other multiplied by a constant

- If y varies directly with x, the y = kx, where k is the constant

 of variation

- The equation y = kx is represented graphically by a line

- If the value of x = 0 then the value of y must be equal zero, then <u><em>the </em></u>

<em>  </em><u><em>line which represented the direct variation must be passes through </em></u>

<em>   </em><u><em>the origin</em></u>

* Lets look to the answer to find the correct statement

a. The graph is a curve ⇒ Not true ⇒The graph must be line

b. The graph increases from left to right ⇒ Not true ⇒ maybe if the

    graph is a line there is no mention about the type of the graph

c. The points on the graph are connected ⇒ Not true ⇒ there is no

    mention about the type of the graph

d. <u><em>The points of the graph form a straight line, and the line must pass</em></u>

<em>     </em><u><em>through the origin</em></u> ⇒ <em>True</em> ⇒ as we said above

* <em>The answer is statement d</em>

Will mark Brainliest if you help me quickly! Helppppp!
ANTONII [103]

Answer:

Let C represent the total cost of each deal  

Let T be the number of trips down the water slide

C = 32        for the 1st deal since the cost is the same regardless of how much she rides  

C = 18 + T  for the 2nd deal

To find when the two costs are equal set them equal to each other and solve for T

32 = 18 + T

T = 14  trips

The cost must be $32 since that is the only cost possible for the 1st deal
