Find the x-intercepts of f(x) = x2 + 7x + 10.

Mathematics
1 answer:
Andrej [43]4 years ago
6 0

Answer:

x = - 5, x = - 2

Step-by-step explanation:

Given

f(x) = x² + 7x + 10

To find the x- intercepts let f(x) = 0, that is

x² + 7x + 10 = 0 ← in standard form

(x + 2)(x + 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x + 5 = 0 ⇒ x = - 5

The x- intercepts are (- 5, 0) and (- 2, 0 )

What is the equation of a circle whose radius is 16 units and center is at (2,-5)?
STatiana [176]

Answer:

  • The general equation of the circle is
  • ( {x - a})^{2}  +  ({y - b})^{2}  =  {r}^{2}  \\ therefore \:  we \: \: have \:  \\ ( {x - 2})^{2}  + (y - ( - 5)) {}^{2}  =  ({16})^{2}  \\  ({x - 2})^{2}  + ( {y + 5})^{2}  = 256

2. El perimetro de un rectangulo es 64 pies. Su largo es 12 pies mas que 3 veces su ancho. Halla las dimensiones del rectangulo
Afina-wow [57]
Ancho= x
Largo= 3x+12 ("12 pies más (adición) que 3 veces (multiplicación) su ancho (x)")

<span>En el problema incluyen el perímetro (la suma de todos los lados de una figura). </span>En un rectángulo, los lados opuestos son congruentes, así que para calcular el valor de x, tenemos que sumar nuestras ecuaciones.

(3x+12)+(3x+12)+x+x=64
8x=64-24
x=40/8
x=5

Luego lo único que queda hacer es substituir el valor de x en cada ecuación para calcular los valores que te piden.
