Answer: not a function
Step-by-step explanation:
the input x=5 has two outputs, y=3 and y=1
(x,y)
Solution for 1/5(5x+12)=18 equation:
<span>x in (-oo:+oo)
(1/5)*(5*x+12) = 18 // - 18
(1/5)*(5*x+12)-18 = 0
1/5*(5*x+12)-18 = 0
1/5*(5*x+12)-18 = 0
x-78/5 = 0
x-78/5 = 0
x-78/5 = 0 // + 78/5
x = 78/5
x = 78/5

Answer:
dy/dx = -5y - y/x
Step-by-step explanation:
In xy + 5x = 30
Differentiating xy implicitly
y + xdy/dx
Assuming u = xy
In xy = In u
Differentiating In u = 1/u = 1/xy
Differentiating 5x = 5 and differentiating a constant (30) = 0
1/xy(y + xdy/dx) + 5 = 0
(y + xdy/dx)/xy = -5
(y + xdy/dx) = -5xy
xdy/dx = -5xy - y
dy/dx = = (-5xy - y)/x
dy/dx = -5y - y/x
For this case we have that by definition, the Pythagorean theorem states that:

Where:
a, b: Are the legs
c: It is the hypotenuse
According to the figure we have to:

Substituting in the formula we have:

Answer:
Option D
