Answer 2

Which system of equations has exactly one solution?
2 x minus 4 y = 8. x + y = 7.
3 x + y = negative 1. 6 x + 2 y = negative 2.
3 x + 3 y = 3. Negative 6 x minus 6 y = 3.
3 x minus 2 y = 4. Negative 3 x + 2 y = 4.

Answer 3

Can you upload the screenshot? It would be a lot easier

Answer 4

i thinks it A

Answer 5

A.) 2 x minus 4 y = 8. x + y = 7.

2x-4y = 8

x+y=7

This has one solution

B.) 3 x + y = negative 1. 6 x + 2 y = negative 2.

3x+y = -1

Multiply by 2

6x +2y = -2

This is the second equation so it has infinite solutions

C.) 3 x + 3 y = 3. Negative 6 x minus 6 y = 3.

3x+3y =3

Multiply by -2

-6x-6y = -6

The equation is the same but the constant, which means they are parallel lines, they have zero solutions

D.) 3 x minus 2 y = 4. Negative 3 x + 2 y = 4.

3x -2y = 4

Multiply by -1

-3x +2y = -4

The equation is the same but the constant, which means they are parallel lines, they have zero solutions

Answer 6

thats another problem

Answer 7

OK so what is the first thing that we have to do?

Answer 8

ask google

Answer 9

Which system of equations below has no solution?
y = 4x + 5 and y = 4x – 5
y = 4x + 5 and 2y = 8x + 10
y = 4x + 5 and y = One-fourthx + 5
y = 4x + 5 and y = 8x + 10
