Question

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

−40 > 5 over 9 (F − 32) > 125; −40 > F > 257

−40 < 5 over 9 (F − 32) < 125; −40 < F < 257

−40 < 5 over 9 (F − 32); −40 < F

5 over 9 (F − 32) < 125; F < 257

Answer 1

which one are you leaning towards?

Answer 2

Honestly I have no idea on this question. I know I got the others right but I am stuck on this one

Answer 3

I thought maybe the 1st one but I still don't think that's right

Answer 4

logically, if one range is between 2 values, the equivalent cannot be outside those same values. so it is not the first one

Answer 5

Okay

Answer 6

following that same line of thought; the equivalent has to be between 2 values, and not be openended right?

Answer 7

Yeah. Is it the third one?

Answer 8

is the third one openended?

Answer 9

By open-ended do you mean ending with a number like this <257

So if that's what you mean then it would have to be B or D

Answer 10

yes, by openended i mean that it is missing a limiting point on both sides.


<----a b--->
open at both ends


a <----------------> b
closed on both ends


<---------------- b
open ended


a --------------->
open ended

Answer 11

i would say that options A and B have the best chance to be closed; but option A is actually open at both ends so its out

Answer 12

Okay. Which do you think it is? I will just guess out of B C or D if you don't have a certain idea

Answer 13

You there?
