Trent is finally starting to out-grow his older sister. His current height (in inches) is 25 less than twice his sister Rebecca's height. If Trent is currently 60 inches tall, write an equation you can use to determine Rebecca's height, h.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

hello,

as   long as they add up to 180 its correct.
