Solve the following system pf equations

Mathematics
1 answer:
mr Goodwill [35]3 years ago
5 0

Answer:

Step-by-step explanation:

If you need to do this by graphing, you need to change the format of each equation into slope intersect form

start with 3x-2y=-24

-2y=-3x-24

y=-3/2x+12

To graph this, the y intersect (where it crosses the y axis) is 12 and from there the slope is -3/2

For the next equation,

-3x-y=6

-y=3x+6

y=-3x-6

So the y intersect is -6 and the slope is -3.

Once you graph both of these, the point where both lines cross AKA the intersecion is the solution to the problem.

You must find the least common multiple of their schedules.

The numbers 3 and 2 are their own prime factors, so the least common multiple of 3 and 2 is 6.

Six weekends must pass until they can both have someone over on the same night.

The number line below shows that the first time their sleepovers coincide is Week 6.
