C= 5 9 (f−32) the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true? a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of 5 9 degree celsius. a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit. a temperature increase of 5 9 degree fahrenheit is equivalent to a temperature increase of 1 degree celsius. a) i only b) ii only c) iii only d) i and ii only good luck lol

D) I and II only

Step-by-step explanation:

C= 5/9(F−32)

If F goes up 1 degree  (33 degrees)

C= 5/9(33−32)

C = 5/9 *1 = 5/9

So  the first 1 is true

If C goes up 1 degree  

1= 5/9(F−32)

Multiply each side by 9/5

9/5 = 9/5 * 5/9 (F-32)

9/5 = (F-32)

1.8 = F-32

Add 32 to each side

33.8 =F

The change from 33.8 to 32  is 1.8 degrees F  so 2 is true

If F goes up 5/9 degree  

C= 5/9(5/9)

C = 25/49

False

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

whatvare the choices
