Question

Please answer the question it’s for my math SAT

Answer 1

D!!!!

Explanation:

Answer 2

Answer: D.

This is tricky.

Think of the equation as an equation for a line

where in this case.

`C=5/9(f-32)`

or

`C=5/9f-5/9(32)`

You can see the slope of the graph is
`5/9` which means that for an increase of 1 degree Fahrenheit, the increase is
`5/9`.

`c=5/9(f)`

`c=5/9(1)=5/9`

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of
`9/5` Degrees Fahrenheit

`c=5/9(f)`

`1=5/9(f)`

`f=9/5`

Since
`9/5=1.8` Statement 2, is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of
`5/9` degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

`c=5/9(f)`

`c=5/9(5/9)`

`c=25/81` which is ≠ 1)

An increase of
`5/9` degree Fahrenheit leads to an increase of
`25/81`

not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.
