Question 1
Use substitution t solve the system of equations
5x + y = -24
x + 3y = -2
A: x = -5, y = -1
B: x = 5, y = 1
C: x = -5, y = 1
D x = 5, y = -1
Question 2:
Use substitution to solve the systems of equations. How many solutions are there?
1/2 x -1/3 y = 5
x = 2/3 y + 10
A: there are no solutions
B: there is one solution.
C: there are infinitely many solutions.
D: it is not possible to determine the number of solutions.
Question 3
y = 4.5x + 7.5
y = -3.5x - 4.5
A: x = -1.5, y = -0.75
B: x = 1.5, y = 0.75
C: x = 1.5, y = -0.75
D: x = -1.5, y = 0.75
Questions 4:
When using substitution to solve a system of equations, how can you tell when a system has no solution? Use the drop-down menus to explain your answer.
A system has no solution when the resulting equation is always. A True Or False? Next x = 4 4 = 5 4 = 4 is an example of this type of equation.
Question 5:
Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1,000 was collected and 150 tickets sold. Use substitution to solve a system of equations to find how many of each kind of ticket were sold? Enter your answers in the boxes.
How many student tickets were sold?
How many adult Tickets were sold?
