El conductor con su bus viaja de Tunja a Bucaramanga pasando por San Gil. El trayecto de Tunja a San Gil mantuvo una velocidad constante de 74 kilómetros por hora; se baja en San Gil a descansar unos minutos y luego continúa su trayecto de San Gil a Bucaramanga a una velocidad constante de 46 millas por hora. Sabiendo que d1 es la distancia desde Tunja a San Gil y d2 es la distancia de San Gil a Bucaramanga el conductor realiza el siguiente procedimiento para calcular el tiempo total del viaje (sin tener en cuenta el tiempo que duró el descanso en San Gil)

y=mx+b

step-by-step explanation:

m slope, b y-intercept

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

its adding 5.5 each time
