1:

Select the system of equations that corresponds to the given word graph.

Graph of two lines. Both lines have a negative slope and go through the points (2,0) and (0,4)

1. 4x + y = 6

6x + 3y = 6

2. −3x + y = 2

4x + 2y = 4

3. 2x + y = 4

6x + 3y = 12

4. 4x + 2y = 6

6x + 3y = 12

2:

Use a system of equations to solve the following problem: Fairview High School has a total of 92 boys and girls who play sports. If the number of boys is 17 more than twice the number of girls, how many boys play sports at this high school?

1. 25

2. 75

3. 67

4. 84

Trevor solved the system of equations below. What mistake did he make in his work?

2x + y = 5

x − 2y = 10

y = 5 − 2x

x − 2(5 − 2x) = 10

x − 10 + 4x = 10

5x − 10 = 10

5x = 0

x = 0

2(0) + y = 5

y = 5

1. He should have substituted 5 + 2x

2. He combined like terms incorrectly, it should have been 4x instead of 5x

3. He subtracted 10 from both sides instead of adding 10 to both sides

4. He made no mistake

4:

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

2x − 3y = 3

5x − 4y = 4

1. −1

2. 0

3. x can be any number as there are infinitely many solutions to this system

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

Part 1: Decide whether you would use the graphing, substitution, or elimination method to solve the following system of equations. Explain, in complete sentences, why you chose that method.

Part 2: Solve the following system of equations and show all of your work.

2x + 5y = −3

−15x − 5y = −10

I tried these questions by myself and got all but the part 1 and 2 right how many can u get right??

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♥
