Determine whether the given lines are parallel, perpendicular or neither. 5x + 4y = 3
5x – 4y = -3

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

If you solve for y and graph it you'll find out that these equations will be perpendicular.

The first equation when solved for y will be...

The second equation when solved for y will be...

If you really need to graph it go ahead but if you're to lazy like me you can know by looking at the equations. If you look at the y-intercept they are the same that means they share a common point. So they can't be parallel if they are touching. Now if we look at the slope one is positive and the other is  negative that means one is pointing upwards and the other one is pointing downward, that makes them perpendicular.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
