Answer:

  (a)  -2

Step-by-step explanation:

Put -1 where x is and do the arithmetic.

  f(x) = x³ +2x² -3

  f(-1) = (-1)³ +2(-1)² -3

  f(-1) = -1 +2 -3 = 1 -3

  f(-1) = -2

The answer=>

For this,we need to know what's Middle splitting method

  • In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as <em><u>px + qx and</u></em> get desired factors by grouping the terms.

Step-by-step explanation:

9x {}^{2}  - 24x + 16 \\  =  > 9x {}^{2}  - 12x - 12x + 16 \\  =  > 3x(3x - 4) - 4(3x - 4) \\  =  > (3x - 4)(3x - 4) \\ so... \\ x = eitherway \: 4

i.e

Alpha= Beta = 4

Y+2=1/3 (x+1) please can you help
miskamm [114]

Equation:

y + 2 = 1/3(x+1)

Assuming you are solving for Y:

y + 2 = 1/3(x) + 1/3(1)

(y + 2) - 2 = (1/3x + 1/3) - 2

y = 1/3x + 1/3 - 2

<u>y = 1/3x - 5/3</u>

El jefe de ventas comenta con tu padre que los 9.000 vehículos del mes pasado suponen unos buenos resultados, pero que este mes
Alja [10]

Answer:

900

Step-by-step explanation:

10% de 9000 es 900

Trabajando el 10% de 9000

Escribe 10% como 10100

Dado que, encontrar la fracción de un número es lo mismo que multiplicar la fracción por el número, tenemos

10100 de 9000 = 10100 × 9000

Por tanto, la respuesta es 900

Si está utilizando una calculadora, simplemente ingrese 10 ÷ 100 × 9000, lo que le dará 900 como respuesta.
