1:

Systems of equations with different slopes and different y-intercepts have one solution.

1. Always

2. Sometimes

3. Never

2:

The three Math Idol judges have been eliminating contestants all day! The number of one-step equations and two-step equations who have been eliminated today is equal to 840! If three times the number of one-step equations minus twice the number of two-step equations is equal to 870, how many one-step equations auditioned today?

1. 330

2. 510

3. 520

4. 660

3:

For the following system, if you isolated y in the first equation to use the Substitution Method, what expression would you substitute into the second equation?

4x − y = 8

2x + 3y = 9

1. 8 − 4x

2. 8 + 4x

3. −8 + 4x

4. −8 − 4x

4:

What is the value of the x variable in the solution to the following system of equations?

4x + y = 8

x − 2y = 2

1. 0

2. 2

3. There is no x value as there is no solution to this system

4. x can be any value as there are infinitely many solutions to this system

5:

Systems of equations with the same slopes and different y-intercepts have no solution.

1. Always

2. Sometimes

3. Never

6:

If you wanted to eliminate the y variable in the following system, what could be your first step?

x − y = 6

4x − 3y = 12

1. Add the two equations together

2. Multiply the first equation by −4

3. Multiply the first equation by 3

4. Multiply the first equation by −3

i have done these myself and got all of them right how many can u get??

this is not hw its just easy points for u just please show step by step

remember the 1 w/ the most info and the correct answer gets the most points(the best answer choice)

thanx♥
