Question

4x + 6y > or = 10

Answer 1

Graph the inequality. ive already tries this problem got it wrong and im not sure how to even put this in my calculator

Answer 2

first lets solve it for y, what do you get? >= sign stays constant the whole time

Answer 3

what sort of calculator?

Answer 4

TI-84 Plus Silver Edition Texas Instruments and i dont know how to slove for y

Answer 5

can you graph equations like y = 3x + 5 ?

Answer 6

yes

Answer 7

we need to get your equation looking like y = something

Answer 8

-4x + 4x + 6y >= 10 - 4x
6y >= 10 - 4x divide by 6
y >= - 2/3x + 5/3

graph this line as if it was y = - 2/3x + 5/3

Answer 9

so i subract y from both sides or no

Answer 10

no

Answer 11

I subtracted 4x from both sides first, then divided by 6 to get y be itself

Answer 12

well im screwed then cause thats all i know how to do

Answer 13

because it is >= and not just > the line will be solid instead of dashed. This means that the solution can be anywhere on this line, hence the >"=". Now to graph the > part we need to shade above or below the line. This is because all of those points are also possible solutions. So let's think should we shade above or below?

Answer 14

thanks for the medal even though i dont deserve one lol

Answer 15

just saying im never going to understand this when two people are trying to explain this at once

Answer 16

ChemE is on the money stay with that thread.

Answer 17

@1on1 will you help explain what im supposed to do

Answer 18

I'll try.

Answer 19

how do i put the equation i have in y = terms

Answer 20

With inequality graphs it is important to graph the line that is on the edge of the coloured in region.

Answer 21

Firstly pretend that there is not an inequality sign and make it an = sign.

Answer 22

i have to unswer choices in down to but idk which one it is and i cant draw these graphs out they come out looking like biggie

Answer 23

two answer*

Answer 24

no offense but i didnt want the answer i wanted to learn how to do it cause i have more like this

Answer 25

I tried to teach you the correct way but you wanted to learn from somebody who is fuzzy on this topic. Read my thread above and you will have the explanation.

Answer 26

@ChmE i didnt understand your thread you posted

Answer 27

still there jj25?

Answer 28

Should have said so.

steps:
1. Get the equation in slope-intercept form. y = mx + b
a) Keep the inquality sign constant through the problem
b) If you have to divide by a negative number the inequality sign flips
2. Graph the line
a) if the sign is < or > then the line will be dashed meaning the solution is not part of the line
b) if the sign is <= or >= then the line will be solid meaning the solution is part of the line
3. Shade above or below the line, start on the y-axis
a) if y>x you shade above. This means that all the y values greater than this line are possible solutions
b) if y<x you shade below. This means that all the y values less than this line are possible solutions
