Question

Please Help, I am having problems trying to figure out this last question for my assignment..... Please Help I will give Medal!!

Answer 1

In a certain town the temperature, x in degrees Celsius on a certain day is described by two statements:

If 3 times the temperature is increased by 2, the temperature is still less than 14°C.
Twice the temperature minus 7 is greater than 11°C.


Part A: Create a compound inequality to represent the temperature range.

Part B: Can the temperature in this town be 5°C? Justify your answer by solving the inequalities in Part A.

Part C: The average temperature in another town is 3°C but the actual temperature is within 4°C of the average. Write and solve an inequality to find the range of temperature in this town.

Answer 2

@skullpatrol Please help me

Answer 3

I have Part A and B I just need part C @skullpatrol please can you help me???

Answer 4

A) If 3 times the temperature is increased by 2, the temperature is still less than 14°C.
Twice the temperature minus 7 is greater than 11°C.
3x+2<14
2x-7>11

B) Can the temperature in this town be 5°C? Justify your answer by solving the inequalities in Part A.
3x<12
x<4
2x>18
x>9

If x is always either less than 4 or greater than 9 the temperature cannot be 5.

Answer 5

Okay Thanks But I have Part A and B I need C can you help me with that @whatchalookinat

Answer 6

C) I believe it is x-4<3<x+4. However I'm not sure so please don't take my word for it.

Answer 7

This is what I have for C x<= 3*C or x => 4*C but I wasnt Sure either

Answer 8

@whatchalookinat Would my Answer for C be correct or are you not sure?

Answer 9

@zepdrix @e.mccormick Can you please check if my answer for C is right?

Answer 10

@Moonlight10198
Can you help?

Answer 11

@zepdrix @jayz657 can either of you help?

Answer 12

The `average` temperature in the town is \(\Large 3^o\).

The `actual` temperature can deviate up or down 4 degrees from the average.
So the actual temperature can range anywhere from \(\Large 3^o-4^o\) to \(\Large 3^o+4^o\).Like watcha had said.

Answer 13

zepdrix got this

Answer 14

Err I guess in the middle of our inequality we would stuff our Temperature variable, not a 3.\[\Large -1\lt T\lt 7\]

Answer 15

Does that make sense lissie? :o

Answer 16

I suppose yes

Answer 17

x<= 3*C or x => 4*C

This is what I had gotten

Answer 18

:S

Answer 19

x-4<T<x+4 Would it be like this @zepdrix

Answer 20

Yes you can write it like that :)
But put x=3.

The temperature can be 4 less than 3,
Or it can also be 4 greater than 3.

the x doesn't really tell us much :d

Answer 21

So would it be 3-4<T<3+4
then -1<T<7
Is that what you were trying to explain @zepdrix

Answer 22

So if the average temperature is 3.
And our actual temp can be 4 above that = 7
Or 4 below that value = -1

Then yes our temperature is sandwiched between -1 and 7.
Looks good!

Answer 23

Haha! Thanks For All of your help @zepdrix @whatchalookinat Both helped a bunch! Lets hope its right!

Answer 24

yay team \c:/

Answer 25

Thanks again guys! Now to go to sleep Im tired :/
