Write equation in slope intercept form
An equation in slope intercept form is:

Substitute values for m and b

63/80 x 100 = 78.8%
You divide normally but multiply by 100 (moving the decimal over two places).
-3 2/3 I just changed the mixed number into a improper fraction
given h = 600 - 16t ( add 16t to both sides )
16t + h = 600 ( subtract h from both sides )
16t = 600 - h ( divide both sides by 16 )
t = 
when h = 400
t =
=
= 12.5 seconds
(3 + 2i)(5 + i)
15 + 3i + 10i + 2i^2
15 + 13i - 2
13 + 13i
