Question

Pleeease help me. I need help with this one.

Answer 1

Answer:

Ravi and Courtney

Step-by-step explanation:

Simplifying the equations

Penny

• 2x - y = -1
• y = 2x + 1

Ravi

• 2x + 3y = 3
• 3y = -2x + 3
• y = -2/3x + 3

Courtney

• -4x - 6y = -6
• 6y = -4x + 6
• y = -2/3x + 3

Edwin

• 6x + 6y = 9
• 6y = -6x + 9
• y = -x + 9

Ravi and Courtney would have infinitely many solutions because they are the same equation.

Answer 2

Answer:

Ravi and Courtney have the same equation so they will have infinetely many solutions.

Step-by-step explanation:

Step 1:  Solve each equation for y

Penny → $2x - y = 1$

           → $-y + 2x - 2x = 1 - 2x$

           → $(-y) * -1 = (1 - 2x) * -1$

           → $y = 2x - 1$

Ravi → $2x + 3y = 3$

       → $3y + 2x - 2x = 3 - 2x$

       → $(3y)/3 = (3 - 2x)/3$

       → $y = -2/3x + 1$

Courtney → $-4x - 6y = -6$

                → $-6y - 4x + 4x = -6 + 4x$

                → $(-6y)/-6 = (-6 + 4x)/-6$

                → $y = -2/3x + 1$

Edwin → $6x + 6y = 9$

           → $6y + 6x - 6x = 9 - 6x$

           → $(6y)/6 = (9 - 6x)/6$

           → $y = -x + 1.5$

Answer: Ravi and Courtney have the same equation so they will have infinetely many solutions.
