Question

1.Graph the system of inequalities. Then use your graph to identify the point that represents a solution to the system. x > 3 y ≤ 2x – 5
(5, 6)


(4, –1)


(–3, –1)

(1, 11)
2. Graph the system of inequalities. Then use your graph to identify the point that represents a solution to the system.

x – y ≥ 7
x + 2y < 5

A. (6,1)
B. (8,-1)
C. (6,2)
D. (6,-2)

3. Graph the system of inequalities. Then use your graph to identify the point that represents a solution to the system.

3x – 4y > 0
x – 5y > 0

A. (-4,-2)
B. (6,0)
C. (0,0)
D. (6,2)

Answer 1

The formatting kinda confuses me, sec.

Put them into y = mx + b or in this case with an inequality. Then graph them.

Answer 2

On #1, it says x >3 ... are you missing a y?

Answer 3

Answer 4

No

Answer 5

Hmph, what grade is this? Lets move onto the rest, we'll get back to #1

Answer 6

okay and grade 8th

Answer 7

Hmm, x – y ≥ 7
x + 2y < 5

x – y ≥ 7
-x -x

-y ≥ -x + 7
/-1 /-1 /-1

y ≤ x - 7 same as -> y ≤ x/1 -7 .. the slope is 1 and the y intercept is (0,-7)


x + 2y < 5
-x -x

2y < -x + 5
/2 /2 /2

y < -x/2 + 2.5 .. the slope is -x/2 (rise/run) and the y intercept is (0,2.5)

Now plot them on a graph

Answer 8

if you substitute (0, 0) for x and y, and get a true statement, you must shade on the side that includes the origin.

Answer 9

Okay thank you very much ^-^

Answer 10

Yw, can you continue or do you still need help

Answer 11

I would still like some help please, math is very hard for me.

Answer 12

k

Answer 13

I must warn you, i'm a horrible artist so using a graphing calculator is suggested >.<

Answer 14

lol thats okay

Answer 15

The solutions lie where they over lap, so by plugging in any pair will give you a true statement
