2. Eq1: Y = x+6.
Eq2: Y = 2x.
In Eq1, replace Y with 2x and solve for X.
2x = x+6.
2x-x = 6
X = 6.
In Eq2, replace X with 6 and solve for Y.
Y = 2*6 = 12.
Solution Set: (x,y) = (6,12).
3. Y = 3x - 6.
1)A farmer plans to create a rectangular garden that he will enclose with chicken wire. The garden can be no more than 30 ft wide. The farmer would like to use at most 180 ft. of chicken wire. Write a system of linear inequalities that models this situation.
2) Determine the solution of the system.
y = x + 6
y = 2x
3)Write an equation of a line whose graph is parallel to the graph of y = 3x – 10.
