Systems of Equations/Inequalities

Front

What is the solution? Options: (1, -1), (-1, 1), (0, -2), (0, 1)

Back

(1, -1)

Front

If a system of equations has no solution, what does the graph look like?

Back

parallel lines

Front

There are 50 donkeys and chickens on a farm. There are a total of 174 legs. Which system of equations can be used to figure out how many of each animal the farm has?

Back

d + c = 50
4d + 2c = 174

Front

Use substitution to solve for x and y
3x + 2y = 16
7x + y = 19

Back

(2,5)

Front

Alexandra's haircuts and hair dyes: 3 haircuts + 2 hair dyes = 315 minutes; 2 haircuts + 4 hair dyes = 450 minutes. Which system of equations represents the situation?

Back

3x + 2y = 315; 2x + 4y = 450

Front

Your family goes to a southern style restaurant for dinner. There are 6 total people in your family. Some order chicken for $14 and the rest order steak for $17. The total bill is $99. Write a system that could represent this situation.

Back

c + s = 6
14c + 17s = 99

Front

Solve using substitution.
x - 2y = 2
3x + 4y = 3

Back

(1.4, -0.3)

Front

Solve using substitution.
2x - 2y = 2
y = -5x + 14

Back

(2.5, 1.5)

Front

Are the points on the boundary line part of the solution set?

Back

Yes, they are part of the solution set

Front

How can I tell if an inequality will have a solid line?

Back

The symbol has "or equal to."
