You want to go to the skate park, and you have two options:
Tcecarenko [31]

Answer:

See Explanation

Step-by-step explanation:

<u>Define the variables</u>

Let the entry fee be c and the hourly rate be m

Let the number of hours be x and the total amount be y

<u>Work to solve</u>

For Sami's skate

c = 6 and m = 2

For Brad's skate

c =10 and m = 1

<u>The equations</u>

The equation is derived using: y = mx + c

For Sami's skate

y = 2x + 6

For Brad's skate

y = x + 10

<u>When the cost are the same</u>

To do this, we equate both expressions

i.e.

y = y

2x + 6 = x + 10

2x -x = 10 - 6

x = 4

i.e. the cost are the same at the 4th hour

<u>What is the cost</u>

Substitute 4 for x in any of the equations

y = x + 10

y  = 4 + 10

y  = 14

<em>The cost is $14.00</em>

If y varies directly as x and y=32 when x=4. find the constant of variation​
Llana [10]

Answer:

k = 8

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 32 when x = 4, then

32 = 4k ( divide both sides by 4 )

8 = k
