A una persona le ofrecieron dos trabajos de vendedor. En la empresa A, le ofrecieron al mes un sueldo base de $6 000 más una com
Dominik [7]

Concluimos que a partir de 21 piezas se gana más en la empresa B.

<h3>¿Cuanto debe vender para que le paguen más en la empresa B?</h3>

Si definimos el número de piezas vendidas como x, la cantidad que le pagan en la empresa A es:

A(x) = $6000 + $20*x

Y lo que le pagan en la empresa B es:

B(x) = $6000 + x^2

Queremos ver para que valor de x, se da que B(x) > A(x).

Entoces resolvamos esa inequación.

6000 + 20*x < 6000 + x^2

20x < x^2

20 < x

x debe ser más grande que 20, entonces concluimos que a partir de 21 piezas se gana más en la empresa B.

Find the inverse function in slope-intercept form (mx+b):<br> f(x)=-3/5x+6
ruslelena [56]

Answer:

f^{-1}(x)=-\frac{5}{3} x+10

Step-by-step explanation:

Steps to find the inverse function:

1) replace f(x) with "y"

y=-\frac{3}{5} x+6

2) solve for x:

y-6=-\frac{3}{5} x\\x=-\frac{5}{3}(y-6)\\ x=\frac{5}{3} (6-y)\\x=-\frac{5}{3} y+10

3) replace "x" with f^{-1}(x), and y with x:

f^{-1}(x)=-\frac{5}{3} x+10

What is the sum of the seven smallest composite numbers which cannot be determined to be composite simply by using the divisibil
ale4655 [162]

Answer:

63

Step-by-step explanation:

A composite number is a whole number. It can be defined as a number that is divisible by 1, itself and other factors. This means a composite number has two or more factors. A prime number cannot be a composite number.

The seven smallest composite numbers are:

4, 6, 8, 9, 10, 14, 16,

Their total sum = 4 + 6 + 8 + 9 + 10 + 14 + 16 = 63

Therefore, the sum of the seven smallest composite numbers which cannot be determined to be composite simply by using the divisibility rules (for 2,3,4,5,6,8,9 or 10) is 63.
