A school is in session for 6 hours each day. Each class is allotted 3/4 hour, including passing time. How many classes can be fit into the school day?
<span>6 / (3/4) = </span>
<span>6 * (4/3) = 24/3 = 8 classes</span>
Answer:
Step-by-step explanation:
Alternate forms:
x^2 + y (y + 4) = 5
x^2 + y^2 + 4 y - 5 = 0
Solutions:
y = -sqrt(9 - x^2) - 2
y = sqrt(9 - x^2) - 2
Integer solutions:
x = ± 3, y = -2
x = 0, y = -5
x = 0, y = 1
Implicit derivatives:
(dx(y))/(dy) = -(2 + y)/x
(dy(x))/(dx) = -x/(2 + y)
