1. use the graph to state the solution for the system. (in other words, what is the solution for the system? )
x + 2y = 4 (line a)
3x β 2y = 4 (line b)
2. how many solutions are there to the following system of equations? use any method you like, but be sure to show all work.
4x β 14y = 6
β2x + 7y = β3
3. what is the solution to the system of equations? use any method you like, but be sure to show all work.
2x + y = -3
x β 2y = -4
4. the system of equations is coincident. what are the values for b and c that make the system coincident?
4x + 5y = 8
8x + by = c
5. identify whether the statement is true or false. if the statement is false, change one word to transform it into a true statement.
a. two linear equations can have two solutions.
b. lines with no solutions are sometimes parallel.
c. the solution of a system of linear equations is the coordinate point where their graph intersects.
d. equations that have different slopes sometimes have one solution.
ec: write and solve system of equations that can be used to solve the following problem.
each child ticket for a ride costs $3, while each adult ticket costs $5. if the ride collected a total of $150, and 40 tickets were sold, how many of each type of ticket were sold? where c is the number of child tickets and a is the number of adult tickets.
