Question

i have no idea on how to graph inequalities please help

Answer 1

10x+30y\[\le\]1200

Answer 2

#1 - Ignore taht it is an inequality. Gather all your abilities to graph 10x + 30y = 1200

Or, first simplfy your life and graph x + 3y = 120. Tell me why this is hte same line.

Answer 3

u just divided by 10
to get the original just multiply by 10

Answer 4

No need to "get the original". It is exactly the same the way it is. Can you graph that line?

Answer 5

no i dnt know how to

Answer 6

i havent graphed in ages

Answer 7

You're going to have to regain that skill.

y = (-1/3)x + 40 is in what is called "Slope-Intercept" form. It gives you enough inforamtino to graph the line. The y-intercept is the point (0,40). The "40" on the end tells us this. The slope part "-1/3" is a little trickier.

Answer 8

how did u get y=(-1/3)x+40

Answer 9

I showed all the necessary steps in the other thread.

10x+30y = 1200

Divide by 10

x + 3y = 120

Subtract x

3y = -x + 120

Divide by 3

y = (-1/3)x + 40

Past my bedtime. Good luck.
