Members of a senior class held a car wash to raise funds for their senior prom. They charged $3 to wash a car and $5 to wash a p
pashok25 [27]

Answer:the number of cars that were washed is 50

Step-by-step explanation:

Let x represent the number of cars that members of a senior class.

Let y represent the number of pick-up truck or a sport utility vehicle that members of a senior class.

They charged $3 to wash a car and $5 to wash a pick-up truck or a sport utility vehicle and they earned a total of $275. This means that

3x + 5y = 275 - - - - - - - - -- - -1

They washed a total of 75 vehicles. This means that

x + y = 75

Substituting x = 75 - y into equation 1, it becomes

3(75 - y) + 5y = 275

225 - 3y + 5y = 275

- 3y + 5y = 275 - 225

2y = 50

y = 50/2 = 25

Substituting y = 25 into x = 75 - y, it becomes

x = 75 - 25 = 50

What is the rule of the function table?
Leokris [45]

Answer:

y = 3x - 2

Step-by-step explanation:

The 'rule' of a function table is the expression which you use to put in a value of 'x' to get the value of 'y'.  In this case you can look at the table and look for a pattern of 'x' and 'y' values:

       +1  +1  +1  

x = 1    2    3    4  

y = 1    4    7    10

      +3   +3   +3

So, the 'x' is increasing by 1 each time and the y is increasing by 3.  However, what is 'y' when 'x' is 0?  Subtract 1 - 0 to get x = 0 and subtract 1 - 3 to get the value of 'y' or y = 1-3 = -2.  

If we multiply x by 3 and subtract -2:  3x - 2, then we should get our value of 'y' each time:

y = 1(3) - 2 = 1

y = 2(3) -2 = 4

y = 3(3) - 2 = 7

y = 4(3) - 2 = 10
