Considerando la definición de una ecuación, el número desconocido es 50.

<h3>Definición de ecuación</h3>

Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos.

Los miembros de una ecuación son cada una de las expresiones que aparecen a ambos lados del signo igual.

<h3>Número desconocido</h3>

En este caso, "La suma de un número con su mitad es igual a 75" puede ser expresado mediante una ecuación, donde consideras que "x" es la incógnita, que representa el número desconocido.

Teniendo en cuenta que la mitad de un número se calcula dividiendo el número por 2, entonces la ecuación queda expresada como:

x + x÷2= 75

O lo que es lo mismo

x + \frac{1}{2}x= 75

Resolviendo:

\frac{3}{2}x= 75

x= 75 ÷\frac{3}{2}

x= 75×\frac{2}{3}

<u><em>x=50</em></u>

Finalmente, el número desconocido es 50.

What is the best estimate for the number of people in line at 7.A.M
Keith_Richards [23]

We have been given the equation

y=-5.131x^2+31.821x-3.333

It represents the number of people standing to catch a commuter train x hours after 5 A.M.

Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.

y(2)=-5.131(2)^2+31.821(2x)-3.333\\y(2)= 39.785 \approx 40

Therefore, the number of people in the line at 7 a.m. is 40

D id the correct option.

HELP WITH THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
wlad13 [49]

Answer:

B., E.

Step-by-step explanation:

what was the difficulty ? this is just to understand the movement of a thrown rock.

what happens, when you throw a rock through the air ? it will first move up a little bit, reaches a maximum height, and then drops down again.

that is what the graphic shows.

so, can A. be correct ? no. as we move from 0 seconds to the right (time passes) the height of the rock increases first (before decreasing again later on).

can C. be correct ? no, it would mean that the function would look the same on both sides of the x-axis. this is clearly impossible.

can D. be correct ? no, nowhere in the graph is the height (= the functional value, the y to the x) negative.

can F. be correct ? no, we clearly see the maximum height at 1.5 seconds. at 3 seconds the height is actually at its minimum.
