3y+6 is the answer
-9+5(y+3)-2y
-9+5y+15-2y
-9+3y+15
=3y+6
Answer:
y = -1/4x - 1.
Step-by-step explanation:
y = 4x + 5
The slope of this is 4 so the slope of line perpendicular to this line = -1/4.
Using the formula y - y1 = m(x - x1):
y - (-1) = -1/4(x - 0)
y + 1 = -1/4x
y = -1/4x - 1.
The number of points that were possible in the course is 420
What is the required number of points for grade A?
The number of points the student needs to have to make grade A is the student's current points of 371 plus the 7 points remaining to make grade A
Total points for A=371+7
total points for grade A=378
90% of the course total=378
divide both sides 90
90% /90 =378/90
1%=378/90
100%=378/90*100
100%=420
