Step-by-step explanation:

Use substitution to solve the system.

y = 2x+8______equation1

-3x+2y = 13______equation2

sub y into equation 2

-3x+2(2x+8)=13

-3x+4x+16=13

x+16=13

x=13-16

x=-3

sub X into equation 1

y=2x+8

y=2(-3)+8

y= -6+8

y=2

x= -3 y=2

Answer:

The last table given See attached image)

Step-by-step explanation:

Notice that they are asking for the inverse function to the one with the detailed relationship given. The original relationship was assigning to the Domain of number of people attending, the Range of values for charges.

Therefore, the inverse function will be assigning in the opposite way: from the average charges (now the Domain of this relationship), to the number of people attending (now the Range of this relationship). The relationship should also maintain the original element to element connection:

What was:

(20, $10) should now be ($10, 20)

(26, $6.25) should now be ($6.25, 26)

(35, $4) should now be ($4, 35)

This is exactly represented by the last table (see also image attached)
