## shannon342 2 years ago 1. Part 1: Solve the inequality -3x + 4 <= x + 8 and show all of your work. You can use <= to represent the less than or equal to symbol. Part 2: Use complete sentences to describe the graph of the solution from Part 1. 2. Part 1: Solve the compound inequality 3x + 6 > 36 and 3x + 6 <= 54 and show all of your work. You can use <= to represent the less than or equal to symbol. Part 2: Use complete sentences to describe the graph of the solution from Part 1

3. Part 1: Use complete sentences to describe a real-world scenario that could be represented by the inequality 5x + 2y >= 45. Part 2: Choose one ordered pair that is a solution to the given inequality and explain what that ordered pair means in the context of your real-world scenario.

-3x+4<=x+8 -3x-x<=8-4 -4x<=4 x>=-1

3. shannon342

For the part 2 you dont have to worry bout that i can do it i just need the part 1's

4. warningiflirt

3x + 6 > 36 and 3x + 6 <= 54 3x>36-6 3x>30 x>10 3x + 6 <= 54 3x<=54-6 3x<=48 x<=16 10<x<=16

5. shannon342

is that gonna be open circle on 10, closed circle on 16 and shading in between?

6. warningiflirt

|dw:1374868300499:dw|

7. warningiflirt

you should understand how to solve it by now, so solve 5x + 2y >= 45 for me

8. shannon342

It says i need to decribe a real world scenerio

9. warningiflirt

well first you need to simplify/solve it, it well make it easier

10. shannon342

5x+2y >=45 5x-x>=9

11. shannon342

open circle on 9 shading to the right

12. warningiflirt

noooo 5x+2y>=45 5x>=45 x>=9 2y>=45 y>=22.5 so x is 9+ and y is 22.5+

13. warningiflirt

Can you think of a word problem that can be described as 5x+2y>=45 and comes out as x is 9+ and y is 22.5+

14. shannon342

Um not that i know of

15. shannon342

ooo i think ik how bout

16. shannon342

7 \$5 bills and 10 \$2 bills, you would have at least \$45.so and ordered pair would be (7,5)

17. shannon342

18. warningiflirt

no .ill start you off, bob has to pick at least 45 fruits, consisting of apples and oranges, apples are x and oranges are y,

19. shannon342

so the one i put isnt good?

20. warningiflirt

no im not sure you can really graph that with a comp ineq. .......

21. warningiflirt

put this down bob has to pick at least 45 fruits, consisting of apples and oranges, he can pick 5 apples a minuet and 2 oranges a minuet. apples are x and oranges are y. whats the least amount of each he can pick of each to meet the requirement of 45? 5x+2y>=45 5x>=45 x>=9 2y>=45 y>=22.5 so x is 9+ and y is 22.5+ he needs to pick at least 9 apples and 23 oranges.

22. warningiflirt

because u cant pick half an orange

23. warningiflirt

ordered pair is (9,23)

24. shannon342

Thank you so much can u help me with this Which of the following ordered pairs is not a solution to the inequality y greater than or equal to -3x - 2? (0, -1) (0, 0) (-1, 0) (1, 1)

25. shannon342

i got A

26. warningiflirt

sure y>=-3x-2 y+3x>=-2 y>=-2 x>=-2/3 so at least -2/3,-2 so the answer is (-1, 0)

27. shannon342

Thank you soooo much you been alot help to me

28. warningiflirt

you are very welcome :)
