Roxanne graphed this system of equations to find the solution.

Option C is correct.

She is not correct as she use the wrong y intercepts when graphing the equations.

Step-by-step explanation:

Given the system of equations:

        .....[1]

        .           .....[2]

equate these two equations we get;

Add 5 to both sides we get;

Add 2x to both sides we have;

Multiply both sides by 3 we get;

8x = 24

Divide both sides by 8 we get;

x = 3

Substitute the value of x in [2] we have;

y = -2(3)+3 = -6+3

Simplify:

y = -3

Therefore, the correct solution for this given system of equation is (3, -3)

You can see the graph of these equations below.

(C) No, she use the wrong y intercepts when graphing the equations.

Step-by-step explanation:

The given equations are:

and

Now, for graphing both the equations, we use hit and trial method by substituting the various values of x in the given equations,

When x=0, , when x =3,

When x=0, , when x=3,

Thus, the solution of both the equations is (3,-3).

Hence, option (C) No, she use the wrong y intercepts when graphing the equations is correct.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

the answer to 1/4x+5/3x-4=2-1/12x is x=3
