Question

PLEASE HELP!


Select the system of linear inequalities whose solution is graphed.

x ≥ –3, y ≥ x – 2

B.
x > –3, 5y ≥ –4x – 10

C.
x > –3, y ≥ –x + 1

D.
x > –2, y ≥ –x – 1

Answer 1

There is the graph.

Answer 2

Take , we are not here for medals actually, so dont say like that please . :/

Answer 3

what do u think is the answer and why?

Answer 4

haha, rephrasing my words " most of us, not here for medals" :P :D

Answer 5

@jdoe0001

Answer 6

I say A.

Answer 7

I used elimination btw. Would you like to know the technique? It's fast :P

Answer 8

Why? Thanks alot though!

Answer 9

Yes i'd love to!

Answer 10

I'm wrong btw, it's not A. I'll post the way first followed by the answer.

Answer 11

ok

Answer 12

Alright so first I looked at the easiest to see, the vertical line on the left. Obviously, it is a line on x = -3, so D is out. Then you look at the line. What kind of line is it? Is it full, is it dotted? Dotted means the particular value of x itself is not included, so the inequality cannot be a '___ or equal to' so A is out(I made this mistake).

Then you look at the other line, and get its equation. Note: make sure you change the y equation for B in the form of y=mx + c. A fast way to get that equation is to look at the y-intercept first. Here the line passes through y=-2 when x is 0. y-intercept is the value of c in the line equation so...?

Side note: This is the fast way for MCQs. The actual way to work with graphing inequalities is to know which sides of the lines are shaded. Remember this: more is above and to the right, less is below and to the left. :)

Answer 13

I'm sorry I wasn't completely honest when I wrote it. I said I'll give the answer but I'd like to see if you can finish where I left it first.

Answer 14

ok thnx

Answer 15

I tried but cant get it. Can you please tell me the answer?

Answer 16

B. Can you check if it is right?

Answer 17

i still dont get how to check? @Luigi0210

Answer 18

No I mean can you know immediately if that answer is correct or do you have to show to your teacher first?

Answer 19

show teacher

Answer 20

can i just get an answer sorry if im being rude

Answer 21

please

Answer 22

hello?

Answer 23

@wolfe8

Answer 24

Oh sorry. Well I gave my answer to be B earlier because the y-intercept is -2 and when you rewrite the equation in B you get c(y-intercept) to be -2
