Answer:
1. y=3/2x + 12 2. y= 1/4x + 8
Step-by-step explanation:
Use the slope formula to get the slope for each line. Then plug either of the x and y coordinates into the formula y= mx + b and also plug in the slope that you just found and solve for b.
Circumference~(pi)(diameter)~28.26
Area~ (pi)(radius)squared~63.59
I believe these are right
N=-1 distribute then isolate your variable and divide
Answer:

Step-by-step explanation:
Given
Represent point A as thus;

Required
Determine the new position of A, when rotated counterclockwise
The new position will be denoted as A'
When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:

Then, y is negated to give A'

Since he completes 10 minutes each day for five days, he completes 50 minutes.
The percentage of his total requirement would be 50/100 = 0.5 = 50%.
