Solve the system of linear equations by graphing <br> y=1/3x+5<br> y=2/3x+5<br> What is the solution
Tamiku [17]

Answer:

We have the system of equations:

y=1/3x+5

y=2/3x+5

To solve it graphically, we need to graph both lines and see in which point the lines intersect.

You can see the graph below, and you can see that the lines intersect in the point (0, 5)

Now, we can also solve this analytically.

We can use the fact that for the solution, we need y = y.

Then we can write:

(1/3)*x + 5 = (2/3)*x + 5

First, we can subtract 5 in both equations to get:

(1/3)*x = (2/3)*x

This only has a solution when x = 0.

Replacing x = 0 in one of the equations, we get:

y = (1/3)*0 + 5 = 5

Then the solution is x = 0, and y = 5, as we already could see in the graph.

The Miller family visited Mama's Kitchen and ordered 4 hamburgers and 3 medium fries and paid $18.69. James ordered a medium dri
sergij07 [2.7K]
To answer the question, let x be the cost of each hamburger, y be the cost of each medium fries, and z be the cost of each medium drink. The equations that are described in the problem are,
       (Miller )        4x + 3y = 18.69
       (James)       x + 2y + z = 8.66
       (Steven)      2x + y + z = 10.27
Solving simultaneously for the values of the variables give x = 3.36, y = 1.75, and z = 1.8. 
Thus, each hamburger costs $3.36. Each medium fries cost $1.75, and each drink costs $1.8.
