Question

I NEED UR HELP PLEASE ANSWER THIS QUESTION ASAP!!!!!

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 – 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 – 14y = 6
–2x + 7y = –3


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 – 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.

Answer 1

1/ we make -3*and and we have y=-1 and we replaced to have x=6 2/ any answer x=(7y+3)÷2 If we change answer of x in the second equation we get -7y-3+7y=-3 3/ x=-4+2y we change it in the second equation and we get y =1 if replace it in the first we have x=-2 4/ B=10 and C=16 5/ a= false b=true c=true d=true
