A system of equations is graphed on the coordinate plane.
ANTONII [103]
You have 2y=3x-1 and 4y=6x-2. first step is to get the y by itself . first equation you divide everything by 2 which gives you the equation: y= 3/2x-1/2
or y= 1.5x-.5, for the second equation you divide everything by 4, which gives you y=6/4x-2/4 (1/2) or y=1.5-.5. both equations are equal to one another: 
the answer is therefore C Infinitely many solutions.

Tomtit [17]

Answer:

Norton's

Step-by-step explanation:

Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases

Whereas Norton's depot required 30% down payment on installment purchases.

1/3 is fractional value of 33.33%.

therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.
