Write the equation of the line that passes through the given point and is perpendicular to the given line. (0, 3); 3x − 4y = −8

  y = -4/3x + 3

Step-by-step explanation:

3x − 4y = −8

-4y = -3x - 8

y = 3/4x + 2

slope m = 3/4

perpendicular version of it is opposite inverse: -4/3

y-intercept through point (0, 3):

y = mx + b

3 = -4/3(0) + b

b = 3

Use the perpendicular slope with b from above to form new perpendicular equation of line:

y = mx + b

y = -4/3x + 3

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
