Function 1 Answer: 45
Function 1 Explanation: The rate of change (ROC) is basically the same thing as the slope of a graphed function. If you were to graph this table onto a coordinate plane, the slope of the line formed would be 45. (see Function 2 Explanation for more explanations, duh.)
Function 2 Answer: 40
Function 2 Explanation: Functions can be written in slope-intercept form, like this: y = mx + b. The <em>m</em> is the slope, or ROC (above), and the <em>b</em> is called the y-intercept, or where the line crosses the y-axis. The m in that equation is 40...
Hope that helps!! Sorry that took so long...
Answer and Step-by-step explanation:
Simply solve for x (very easy to do).
4x + 9 = 41
<u>Subtract 9 from both sides of the equation.</u>
4x = 32
<u>Divide both sides of the equation by 4.</u>
x = 8
<u>x is equal to 8.</u>

The one u originally clicked (in yellow) is correct. all sides match perfectly with the figure.
So there are 20 people in the family.
The total cost of the tickets were $100. Tickets for adults cost $8 and children cost $4.
To find the answer for the number of adults you need to divide the $100 by $8 and do the same for children but divide the $100 by $4.
So 5 of the family members were adults and 15 were children.
5 adults = $40
15 children = $ 60
