## anonymous one year ago Question 1 (Multiple Choice Worth 1 points) [02.03] Solve for x: |x − 2| + 10 = 12 x = 0 and x = 4 x = −4 and x = 0 x = −20 and x = 4 No solution Question 2 (Multiple Choice Worth 2 points) [02.03] The minimum and maximum temperature for a day in Cupcake Town can be modeled by the equation below: 3|x − 8| + 15 = 18 What are the minimum and maximum temperatures for this day? x = 1, x = 17 x = −7, x = 9 x = 7 x = 9 No solution Question 3 (Multiple Choice Worth 2 points) [02.03] Solve for x: |x| − 8 = −5 x = −13 and x = −3 x = 3 and x = −3 x = 3 and x = 13 No solution Question 4 (Multiple Choice Worth 2 points) [02.03] Solve for x: −3|x + 7| = −12 x = 5 over 3, x = −19 over 3 x = −3, x = −11 x = −3, x = 11 No solution Question 5 (Multiple Choice Worth 2 points) [02.03] Compare and Contrast: Two equations are listed below. Solve each equation and compare the solutions. Choose the statement that is true about both solutions. Equation 1 Equation 2 |5x − 6| = −41 |7x + 13| = 27 Equation 1 has more solutions than equation 2. Equation 1 and Equation 2 have the same number of solutions. Equation 2 has more solutions than Equation 1. The number of solutions cannot be determined. Question 6 (Multiple Choice Worth 1 points) [02.03] Solve for x: −5|x + 1| = 10 x = 0 x = −3 and x = 1 x = −1 and x = 3 No solution

Whoever tells only answers will get Fan and Medal

2. anonymous

umm

3. anonymous

thats confusing af

4. anonymous

:/

5. jiteshmeghwal9

What's so confusing ?

6. anonymous

The forumula you gave me

7. anonymous

Formula*

8. anonymous

actually

9. anonymous

The only questions I can't get are

10. jiteshmeghwal9

ok let x=5 |5|=5 here x=5>0 |-5|=-(-5)=5 because x=-5<0

11. anonymous

The ones that are like: |x − 2| + 10 = 12

12. anonymous

What would I do for that?

13. jiteshmeghwal9

the mod gives us absolute value & its value always comes positive.

14. jiteshmeghwal9

you are asked here to find a value for x which satisfy the eqn.

15. anonymous

I mean is there like a formula for that? cause I get the ones that are like 2|x+7| = 4 or whatever

16. anonymous

I don't get the ones where you add

17. anonymous

Also the ones like 3|x − 8| + 15 = 18

18. jiteshmeghwal9

\[|x-2|+10=12\]\[|x-2|=2\]\[(x-2)=2.....eqn1\]\[-(x-2)=2...eqn2\]i'm sorry for the silly mistake in typing

19. anonymous

Ahhhhhh that makes sense!!!

20. anonymous

You just earned a medal and a fan :D still might need help to make sure I got the right answers

21. anonymous

For 1 is it No Solution?

22. jiteshmeghwal9

\[|x|=x \] for x>0\[|x|=-x\]for x<0 this is ur formula

23. jiteshmeghwal9

no, the answer is option 1 for ur 1st question

24. anonymous

ohh

25. anonymous

For the second one is it No Solution? Cuz I got x=9 and x=8

26. anonymous

?

27. jiteshmeghwal9

no i think u r doing a mistake becuz the answer is x=9 & 7

28. anonymous

hmm

29. jiteshmeghwal9

|x-8|=1 -(x-8)=1 (x-8)=1

30. jiteshmeghwal9

these two eqns will give u the answer for 2nd question

31. anonymous

Ungh I only got like 2 right

32. anonymous

gtg now

33. anonymous

Guys

34. anonymous

Whoever answers the questions gets medal and fan

35. anonymous

36. anonymous

1)A 2)C 3)B 4)B 5)B 6)D I tried, sorry if some are wrong.

37. anonymous

np

38. anonymous

Thank you SO OOOO much

39. anonymous

Wait

40. anonymous

emm I have another small quiz

41. anonymous

can you do that? I already fanned I'll give medal if you can do that

42. anonymous

Sure!!!

43. anonymous

:D
