Question

anonymous · Answer

Plug x = -2, ...

anonymous · Answer

I think I got the answer, is it -18?

anonymous · Answer

Correct :)
g(-2) = 8(-2) - 2
        =  -16   - 2 = -18
@vetdoc I'll expect next time you explain your result like I showed you this time.

The formula for degrees Celsius is: C = five over nine (F − 32), where F stands for degrees Fahrenheit.

Which of the following equations shows the formula correctly solved for F? 

 F = five over nine C + 32 

 F = nine over five C + 32 

 F = five over nine C − 32 

 F = nine over five C − 32

anonymous · Answer

c = 5/9 ( F - 32 ) 
F = 9/5c + 32

anonymous · Answer

just make F subject of formula i guess...

anonymous · Answer

Can you expand from the parentheses?
