Answer:

Felipe dio un paso incorrecto de acuerdo con el sistema de valor posicional al sumar la suma de 1,000 a 39,200. La manera correcta en que Felipe debe abordar esto se muestra en la explicación a continuación.

Step-by-step explanation:

En el sistema de valor posicional; cada número representa una entidad particular; ya sea unidad, decenas, cientos, mil, diez mil etc. En la pregunta dada, el número 39200 indica que 9 está en el valor posicional de mil, es decir, 9000.

Entonces, si Felipe desea cambiar de 8 a 9, entonces necesita restar 9000-8000 = 1000

Sin embargo; si quiere cambiar 9 a cero; entonces restará 9000 de 9000; pero ya que 9 no funciona; Primero debe restar 8000 y luego restar 1000.

What is the minimum value for g(x)=x^2-10x+16? Enter your answer in the box.
Anna71 [15]

Answer:

- 9

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

g(x) = x² - 10x + (- 5)² - (- 5)² + 16

      = x² - 10x + 25 - 25 + 16

     = (x - 5)² - 9 ← in vertex form

vertex = (5, - 9), hence

minimum value = - 9

Step-by-step explanation:

Let's look for key words hidden in these sentences:

1.) The <u>quotient</u> of a number and 2 = The word quotient refers to division

2.) A number <u>decreased</u> by 2 = The word decreased refers to subtraction

3.) 2 <u>times</u> a number = the word times refers to multiplication

4.) 2 <u>increased</u> by a number = the word increased refers to addition

Mark scored 17 points for the home team in a basketball game. His teammates as a group scored p points. As a team they scored 46
ki77a [65]

Answer:

Equation:

17 + p = 46

His teammates scored 29 points

Step-by-step explanation:

We know that Mark scored 17 points and that the entire team scored 46.

Mark's 17 points added to the team's p points will give us a total of 46 points

p = points of his teammates

17 + p = 46

if we want to know how many points his teammates scored we simply have to clear p and solve

17 + p = 46

p = 46 - 17

p = 29

his teammates scored 29 points
