Answer:
x = -2
Step-by-step explanation:
Pull out like factors :
-3x - 6 = -3 • (x + 2)
Solve : -3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x+2 = 0
Subtract 2 from both sides of the equation :
x = -2
Answer:
![$\[x^2 + 22x + 121\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20121%5C%5D%24)
Step-by-step explanation:
Given
![$\[x^2 + 22x + \underline{~~~~}.\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20%5Cunderline%7B~~~~%7D.%5C%5D%24)
Required
Fill in the gap
Represent the blank with k
![$\[x^2 + 22x + k\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20k%5C%5D%24)
Solving for k...
To do this, we start by getting the coefficient of x
Coefficient of x = 22
<em />
Divide the coefficient by 2


Take the square of this result, to give k


Substitute 121 for k
![$\[x^2 + 22x + 121\]$](https://tex.z-dn.net/?f=%24%5C%5Bx%5E2%20%2B%2022x%20%2B%20121%5C%5D%24)
The expression can be factorized as follows;




<em>Hence, the quadratic expression is </em>

Usando conceptos de funciones lineales, se encuentra que hizo 5 cortes.
----------------
Una funcion lineale tiene el seguiente formato:

En que:
- a eres lá inclinacion, o sea, lo que es pago por cada corte.
- b eres el intercepto, o sea, lo pagamiento fixo por día.
----------------
- Pagan $50 por corte realizado, o sea,
. - $25 fixo al día, o sea,

Entonces, la funcion de su recibimiento y, como funcion de su numero de cortes x, es da por:

----------------
- Recibió $275, o sea,

Entonces, el numero de cortes es:

Answer:
m= 102.4
Step-by-step explanation:
Step 1: Multiply both sides by 4.
m/4 =25.6
(m/4)*(4)=(25.6)*(4)
m= 102.4
