Question

Graph the system of inequalities. Then use your graph to determine which points are solutions of the system.

x > 3
y ≤ 2x – 5

Choose all answers that are correct.

A.(4, –4)

B.(4, 8)

C.(5, 10)

D.(6, 0)

E.(6, –2)

Answer 1

@undeadknight26

Answer 2

Do you know how to graph them?

Answer 3

I think you say like since -5 is the y intercept you graph that at 0,-5. And go over 5 and 2 up for 2x. I think

Answer 4

Try desmos graphing.

Answer 5

Whats desmos graphing?

Answer 6

do you really have to graph...because this can be solved without graphing

Answer 7

can u graph x=3
and y=2x-3 :)

Answer 8

You can plug and play but it says to graph lol.

Answer 9

No, They just gave me answer choices @texaschic101

Answer 10

than just plug your answer choices into the 2 inequalities and see which ones are true. Keep in mind, they both have to be true for it to be a solution.

Answer 11

yes u can find the answer by pluggin in the options :)

Answer 12

Do you like multipy and add to find the answer?

Answer 13

Let me do the first one for you.....we will be using (4,-4)...x = 4 and y = -4

now lets begin..
x > 3....sub in 4 for x
4 > 3.....this is true

now we have to check it with the other inequality.
y <= 2x - 5....sub in 4 for x and -4 for y
-4 <= 2(4) - 5
-4 <= 8 - 5
-4 <= 3....this is also true

and since both are true, this is a solution
understand ?

Answer 14

I do understand, this is kinda like what we did yesterday

Answer 15

just be sure that both inequalities are true....because if you sub in your points and only one inequality is true, it is NOT a solution because they both have to be true

Answer 16

Ok

Answer 17

I will attempt to do the next one

Answer 18

Because if you look at the first inequality x > 3....all of the answer choices are correct for this. So I would just check the answer choices with the 2nd inequality.

Answer 19

ok, smart plan

Answer 20

so y <= 2x - 5.......is (4,8) a solution ? Can you tell me ?

Answer 21

I am working in out
8<=2(4)-5
8<8-5
8<3
8 is not less than 3 so false

Answer 22

you are correct....and since (4,8) does not make BOTH inequalities true, then it is NOT a solution. Good job...way to go :)

Answer 23

Thanks ok for the next one
10<2(5)-5
10<10-5
10<5
10 is not less than 5

10>3
Is true, but not for both equations. So False

Answer 24

correct...(5,10) is not a solution

Answer 25

Next one,
0<2(6)-5
0<12-5
0<7
0 is less than 7 so true

0>3
0 is not more than 3 so false
So false

Answer 26

try again.....
x > 3
(6,0)...x = 6 and y = 0........do not get your x's and y's mixed up

Answer 27

x > 3......x = 6
6 > 3...true

and (6,0) also makes the other inequality correct....so (6,0) IS a solution

Answer 28

I'm sorry like you said got my x and y mixed up, helps to get a clean sheet of paper to lol

Answer 29

lol...yes...that helps. To many numbers and letters mixed on one piece of paper will drive you insane

Answer 30

lol, hopefully I'll get this one right

6>3
True 6 is more than 3

-2<2(6)-5
-2<12-5
-2<7
-2 is less than 7 so true
Both equations are true

Answer 31

you got it....(6,-2) is a solution.....nicely done :)

Answer 32

Thanks you so A, D, E

Answer 33

yep.....lol...I had to go back up and look...its A,D,E

Answer 34

Thanks such a great help
