Consider the equation 40x - 25y = 15

david wrote a second equation to create a system that has infinitely many solutions. which of these could be the equation that david wrote?

a) 8x - 5y = 3
b) 8x + 5y = 3
c) 8x + 5y = -3
d) -8x + 5y = -3

A) 8x - 5y = 3

Step-by-step explanation:

To create infinite solutions, the equation has to be the same line

First we can reduce the equation by dividing by 5

40x -25y =15

40/5 x -25/5 y =15/5

8x-5y =3

This is the same line , so if this is the second equation, it will give us infinite solutions

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
