What real world situation models this equation y=1/20x
garri49 [273]
This is a proportional relationship. So any example that shows as x increases, y decreases.
A real life example would be where 
x=time i let the pool drain
y=amount of water left over

As I let the time I let the pool drain increase, the amount of water left in the pool decreases.

HELP PLEASE: Which is the equation of the graphed line written in
maksim [4K]

Answer:

x - y = 0

Step-by-step explanation:

Required

The graph equation

From the graph, we have:

(x_1,y_1) = (0,0)

(x_2,y_2) = (1,1)

The slope of the graph is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{1-0}{1-0}

m = \frac{1}{1}

m =1

So, the graph equation is:

y = m(x - x_1) + y_1

y = 1 * (x - 0) + 0

y = 1 * x

y = x

In standard form, we have:

x - y = 0

Binomial Theorem, proof
IrinaVladis [17]

It follows from the definition of the binomial coefficient:

\dbinom nr=\dfrac{n!}{r!(n-r)!}

So we have

(n+1)\dbinom nr=(n+1)\dfrac{n!}{r!(n-r)!}=(r+1)\dfrac{(n+1)!}{(r+1)!(n-r)!}

That is, (n+1) gets absorbed into the numerator's factorial, and we introduct (r+1) into the denominator. Now, (n+1)-(r+1)=n-r, so we get

(n+1)\dbinom nr=(r+1)\dfrac{(n+1)!}{(r+1)!((n+1)-(r+1))!}=(r+1)\dbinom{n+1}{r+1}

as required.

What is the equation of a line in point-slope form that passes throught -8, 1 and has a slope of 5/6
Flauer [41]

Answer:

5x - 6y +36 =0 is the required equation.

Step-by-step explanation:

(x1, y1) =(-8, - 1)

Slope (m) =5/6

The equation is:

(y - y1) =m(x-x1)

y +1=5/6(x +8)

6y +6 =5x +40

5x - 6y +36 =0 is the required equation.

Hope this helps!!!!
