Question

Can anyone help with some math questions? will medal!

Answer 1

The graph below represents which system of inequalities?

- y > 2x − 3
y > −x − 3
-y < 2x − 2
y < −x + 3
-y ≤ 2x − 2
y > −x + 3
-None of the above

Answer 2

Do u have the graph

Answer 3

i just uploaded it

Answer 4

Nevermind

Answer 5

Oh I was wondering how the answers go but I see now they are in pairs

Answer 6

yeah...do you know how to do it? @AndrewIsHere

Answer 7

@Liv1234

Answer 8

None of the above

Answer 9

So the answer is
-y ≤ 2x − 2
y > −x + 3

OK so what is did was graph each line and both these two answers and the two above them fit the lines graphed. But one thing separated the two answers. The correct answer has a less than or equal to sign on the line that is bolder (not the broken line) and a greater than sign which is represented by the broken line. The other two only had only a greater than or less than sign which would represent two broken lines, which is not shown.

Answer 10

can you explain why? sorry i just need to know so i can understand it

Answer 11

I put all the options in a graphing calculator and none of them was the answer.

Answer 12

Ok graph the one I chose. They definitely match the graph

Answer 13

Nope, it doesn't match

Answer 14

@Error1603 or @tkhunny do you guys know?

Answer 15

It's none of the above.

Answer 16

okay can you guys help with another?

Answer 17

sure

Answer 18

There is a checkbox at the bottom of the exam form that you MUST check prior to submitting this exam. Failure to do so may cause your work to be lost.

Question 1 (Multiple Choice Worth 2 points)

(05.06)

coordinate grid with plotted ordered pairs, point A at negative 5, 4 point B at 4, 7 point C at negative 2, 7 point D at negative 7, 1 point E at 4, negative 2 point F at 1, negative 6 point G at negative 3, negative 10 point H at negative 4, negative 4 point I at 9, 3 point J at 7, negative 4 and point K at 2, 3

The coordinate grid shows points A through K. Which points are solutions to the system of inequalities listed below?

2x + y < 10
2x − 4y > 8
E, F, G, H, J
E, F, G
A, C, D, K
A, E, F

Question 2 (Multiple Choice Worth 2 points)

(05.06)

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 20 child bikes and 6 adult bikes in the week.
No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Question 3 (Multiple Choice Worth 2 points)

(05.06)

The graph below represents which system of inequalities?

graph of two intersecting lines. One line is solid, and goes through the points 0, negative 2 and 1, 0 and is shaded in below the line. The other line is dashed, and goes through the points 0, 3, 3, 0 and is shaded in above the line.
y > 2x − 3
y > −x − 3
y < 2x − 2
y < −x + 3
y ≤ 2x − 2
y > −x + 3
None of the above

Question 4 (Multiple Choice Worth 1 points)

(05.06)

Which of the following points lie in the solution set to the following system of inequalities?

y > −3x + 3
y > x + 2
(2, −5)
(−2, 5)
(2, 5)
(−2, −5)

Question 5 (Multiple Choice Worth 2 points)

(05.06)

The graph below represents which system of inequalities?

graph of two infinite lines that intersect at a point. One line is solid and goes through the points 0, 2, negative 2, 4 and is shaded in below the line. The other line is solid, and goes through the points 0, 2, 2, 0 and is shaded in below the line.
-y ≤ −2x + 3
y ≤ x + 3
-y ≥ −2x + 3
y ≥ x + 3
-y ≤ −3x + 2
y ≤ −x + 2
-y > −2x + 3
y > x + 3

Answer 19

Oh

Answer 20

All of them?

Answer 21

oh no just number 5 and i uploaded the graph

Answer 22

@Princeyboy4

Answer 23

@AndrewIsHere

Answer 24

I'll help

Answer 25

thanks

Answer 26

@xMissAlyCatx

Answer 27

-y > −2x + 3
y > x + 3

Answer 28

Okay well the first line (the solid one) is going to be less than or equal to because the line is solid, and the area shaded is below it (or less than it). It's slope is 2, and it intersects on the y-axis at -2.

The second line (the dotted one) would be greater than because the area shaded is ABOVE the line. The slope is -1 (or -x whatever you prefer to call it) and the point of intersection on the y-axis is 3. :)

Does this help you to determine which equations to use?

Answer 29

no not really..

Answer 30

on the first question i asked do you know which one is right?

Answer 31

I pretty much just told you both of the equations that are correct..

Answer 32

so on the first question i asked the answer is none of the above?

Answer 33

is @Princeyboy4 right on his answers @xMissAlyCatx

Answer 34

Here's the plan.

1) Do the work and find out.
2) It is not clear which final region is selected. Get a better problem statement.

Answer 35

Thank you @tkhunny
