View the step-by-step solution to:

Using the replacement set, find the solutions for the equation. y = 0.5x + 10 Replacement Set: {(-2, 9.5), (0, 10),(3, 11.5),(4, 13)}(Points : 1)...

3. Using the replacement set, find the solutions for the equation.
y = 0.5x + 10 Replacement Set: {(-2, 9.5), (0, 10),(3, 11.5),(4, 13)}(Points : 1)
{(-2, 9.5), (0, 10),(3, 11.5),(4, 13)}
{(-2, 9.5), (0, 10),(3, 11.5)}
{(0, 10),(3, 11.5),(4, 13)}
{ (0, 10),(3, 11.5)}


4. Find the solution, given the replacement set.
5x - 2y = 6 {(-2, -8), (0, -3), (1, -1), (2, 4), (4, 7)}(Points : 1)
{(-2, -8), (2, 4), (4, 7)}
{(-2, -8), (0, -3), (4, 7)}
{(-2, -8), (0, -3), (1, -1)}
{(1, -1), (2, 4), (4, 7)}


5. Solve the equation, using the domain of x = {-1, 0, 2}. Write your solutions as a set of ordered pairs.

2x + 3y = 7(Points : 1)



6. Give the range of x - 2y = 0 for the domain {-1, 0, 4}.(Points : 1)



7. The interest on a loan at an interest rate of 9% over a year is I = (0.09)P, where P is the principle (loan amount) and I is the interest rate. Use a domain in the table to find the interest of these amounts for one year. Write the range only in your solution.

Principle 10 100 1000 10,000 100,000 1,000,000
Interest -- -- -- -- -- --
(Points : 1)



8. What is the independent variable and what is the dependent variable of this relation?

Principle 10 100 1,000 10,000
Interest 2 20 200 2,000
(Points : 1)
