Yes it is a solution because if you take the equation and plug the point in for the x and y :

4 (2) + 3 (3) < 20 
 8 + 9 < 20 
17 < 20
which is true

10 (2) + (3) > 10
20 + 3> 10
23>10
which is also true

Evaluate each expression for a = -2,b = -4.1, and c = 5.<br><br>-c + b – a
laila [671]
For this question, you can substitute in all the values for the variables.
-c + b - a
= -(5) + (-4.1) - (-2)
= -5 - 4.1 + 2
= -9.1 + 2
= -7.1

Hope this helps! :)

As we can see from the table there is a pattern to the whole data in the table. A closer look reveals that when we multiply the number of students, n by the cost per student, c we get a constant number, 72. Let us see what we mean here:

  1. 3\times24=72
  2. 6\times 12=72
  3. 9\times 8=72
  4. 16\times 4.5=72

Thus, the function which models the data is the nc=12.

Now, let us move on to the next part of the question:

If 12 students go on the trip then the cost per student as per this model will be:

\frac{72}{12}=6 dollars=$6

Therefore, out of the given options, the option the correct option is number B.
