The director of a summer day camp estimates that 120 children will join if the camp fee is $250, but for each $25 decrease in the fee, five more children will enroll.
Determine the linear equation that will represent the number of children who will enroll at a given fee. Hint: To write the slope, you need two points on the line. Show all work to receive full credit.

Solution Preview

let x - the fee, y(x) - the number of children with this fee x.
We have y(250) = 120. We have also dy (change in y)=5 if dx (change in ...

1. Given the equation below, find f(x) where y = f(x).
8y(6x - 7) - 12x(4y + 3) + 265 - 5(3x - y + 2) = 0.
2. Solve these linearequations for x, y, and z.
3x + 5y - 2z = 20; 4x - 10y -z = -25; x + y -z = 5
3. The value of y in Question 2 lies in the ran

The techniques for solving linearequations and linear inequalities are similar, yet different. Explain and give an example of both a linear equation and a linear inequality that demonstrates this difference.
1.) Solve and check the linear equation.

1. What similarities and differences do you see between functions and linearequations studied in chapter 3? A linear equation can have one, two, three or more variables and functions are expressed by using math symbols such as y is the output and x is the input.
Are all linearequations functions? Yes, unless the functions eq
