The given table and equation represent the cost for carnival rides.

equation: c = 15.5 + 12f

what ordered pairs are represented in this table? check all that apply.
(7, 99.5)
15.5 + 12(3)
(75.5, 5)
(3, 51.5)
(123.5, 9)

The ordered pairs that are presented are (7, 99.5) and (3, 51.5)

Step-by-step explanation:

We are given the cost function of the carnival rides as

which is a typical linear expression of the form where here , ,    and  . To check if an ordered pair i.e. a point , is represented by the table we can simply plug in the equivalent value in the equation, and check if the result matches the value.

So, lets assume that all points are given correctly and they are as follow:

Now let us check each point with our function as follow:

Point A

So point A is part of the equation.

Point B

So point B is NOT part of the equation.

Point C

So point C is part of the equation.

Point D

So point D is NOT part of the equation.

(7, 99.5) and (3, 51.5)

Step-by-step explanation:

A and D

For this case we have the following table:
 Number of eggs Number of omelets
 18   ?
 9     3
 6     2
 3     1
 We observe that the function is linear.
 The equation of the line is:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)
 m = (6-3) / (2-1)
 m = (3) / (1)
 m = 3
 (xo, yo) = (1, 3)
 Substituting:
 y-3 = 3 (x-1)
 Rewriting:
 y = 3x - 3 + 3
 y = 3x
 For 18 eggs we have:
 18 = 3x
 Clearing x:
 x = 18/3
 x = 6
  
 you can make 6 omelets with 18 eggs
