Becky spent 3/4 of an hour practicing the piano. she spent 1/2 of that time practicing her recital piece. what fractional part of an hour did becky spend practicing her recital piece?

3/8

Step-by-step explanation:

First,

convert  3/4 of an hour to minutes;

If 1 hr = 60 mins

then 3/4 of 1hr =

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
