The formula of a slope:

We have the points (1, k) and (-1, -4) and the slope m = 3/2. Substitute:

Answer:
See below
Step-by-step explanation:
Circle equation standard form
(x-h)^2 + ( y-k)^2 = r^2 h, k is the center
All are centered at 0,0
radii are sqrt(225) = 15 sqrt 49 = 7 and sqrt 178
3y (y is the unknown number but it represents one number only... and also 3y represents 3 multiply by y)
Turn 7/10 into decimal. (0.7)
Keep adding by 0.7 until you get the number closest to 4.1
3.5 is the closest, if we add another 0.7, we get 4.2.
So, he can get 5 sections of 0.7m
Answer: 
Step-by-step explanation:
1. You have thte following equation given in the problem above:

2. Then, you must multiply each sign of the terms inside the parentheses by the negative sign that is outside of the parentheses:

3. Now, you must add the like terms. Then, you obtain the following result:
