A system of equations has infinitely many solutions. If 2y – 4x = 6 is one of the equations, which could be the other equation?
A. y = 2x + 6
B. y = 4x + 6
C. –y = –2x – 3
D. –y = –4x + 6

C

Step-by-step explanation:

When a system of equations has an infinite number of solutions, this means that the equations will be identical.

Convert the given equation to y = mx + b form.

2y - 4x = 6

2y = 4x + 6

y = 2x + 3

Answer A, B, and D don't apply.

Answer C is the answer because if it is the same equation but with a negative sign in front of each term.  If you switch the signs on every single term, you will have the given equation.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
