Question

1. Give the range of x - 2y = 0 for the domain {-1, 0, 4}.
A. Range = {-2, 0, 8}
B. Range = {-1, 0, 4}
C. Range = {5, 0, -2}
D. Range = {-1/2, 0, 2}

2. Solve the equation, using the domain of x = {-1, 0, 2}.
2x + 3y = 7
A. {(-1, 3), (0, 7/3), (2, 1)}
B. {(3, -1), (7/3, 0), (1, 2)}
C. {(5, -1), (7/2, 0), (2, 1)}
D. {(-1, -3), (0, 7/3), (2, 1)}
3. Find the solution, given the replacement set.
5x - 2y = 6 {(-2, -8), (0, -3), (1, -1), (2, 4), (4, 7)}
A. {(-2, -8), (2, 4), (4, 7)}
B. {(-2, -8), (0, -3), (4, 7)}
C. {(-2, -8), (0, -3), (1, -1)}
D. {(1, -1), (2, 4), (4, 7)}

Answer 1

k so for #1. if x is -1, the you need to solve for y by "plugging in" -1

Answer 2

k so would this be the equation: -1-2y=0?

Answer 3

answer to your question, yes
