Answer:

Slope = -3

y-intercept = (0,-4)

Equation: y = -3x-4

Step-by-step explanation:

We can take any two input-output pairs from the table to find the equation of given function.

Linear function is given by:

$y =mx+b$

Here m is the gradient of the functions which is defined as:

$m = \frac{rise}{run} = \frac{y_2-y_1}{x_2-x_1}$

The input-output pairs are:

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

(x2,y2) = (0,-4)

First of all,

$m = \frac{-4-(-1)}{0-(-1)}\\= \frac{-4+1}{1} = -3$

Putting the value of slope in the equation

$y = -3x+b$

Putting (-1,-1) in the equation

$-1 = -3(-1)+b\\-1 = 3+b\\b = -1-3\\b = -4$

The equation will be:

$y = -3x-4$

Hence,

Slope = -3

y-intercept = (0,-4)

Equation: y = -3x-4

en un maratòn participan corredores de todos los continentes 5/6 de los corredores son europeos se sabe que los americanos son l

Marysya12 [62]

Usando proporciones, se encuentra que 400 africanos han participado.

En total, hay x participantes.

$\frac{5}{6}$ de los corredores son europeos, o sea:

$E = \frac{5x}{6}$

Los americanos son la dècime parte de los europeos, o sea:

$Am = \frac{1}{10}E = \frac{5x}{60} = \frac{x}{12}$

Los africanos son la quinta parte de los americanos, o sea:

$Afr = \frac{1}{5}Am = \frac{x}{60}$

En la carrera han inscritos 24 000 participantes, o sea, $x = 24000$ . Por eso, la cantidad de africanos es:

$Afr = \frac{x}{60} = \frac{24000}{60} = 400$
