This can't be graphed. You can't have a slope of 1/x.

(5x + 2)+(7x - 6) equals what

Brums [2.3K]

Answer:

Use F.O.I.L method
First, Outter, Inner, Last

So:

5x*7x= 35x^2

5x*-6= -30x

7x*2= 14x
2*-6= -12

So just add it all up, combine like terms and you have your answer.

35x^2 -16x -12

Tres corredoras salieron a entrenar Amalia recorrio 4,121 km ; Luciana 1,55 km mas que Marta y esta 1 8/2 km menos que Amalia. ¿

Answer:

Luciana y Marta recorren 4,351 kilómetros y 2,801 kilómetros, respectivamente.

Step-by-step explanation:

El enunciado tiene un error tipográfico que induce a equivocación. El enunciado correcto es el siguiente: <em>Tres corredoras salieron a entrenar Amalia recorrió 4,121 kilómetros; Luciana 1,55 kilómetros más que Marta y esta 1 8/25 kilómetros menos que Amalia. ¿Cuántos kilómetros recorrió Luciana y Marta? </em>

Sean $x,y,z$ las distancias recorridas por Amalia, Marta y Luciana, en kilómetros. A partir de la descripción del enunciado tenemos el siguiente sistema de ecuaciones lineales:

Amalia

$x = 4,121\,km$ (1)

Marta

$y = x-1.32\,km$ (2)

Luciana

$z = y + 1.55\,km$ (3)

La solución del sistema de ecuaciones lineales es:

$x =4,121\,km, y = 2,801\,km, z = 4,351\,km$

Luciana y Marta recorren 4,351 kilómetros y 2,801 kilómetros, respectivamente.

Which statement is true of the function f(x) = -3 squared root x

grigory [225]

Using translation concepts, it is found that the function $f(x) = -3\sqrt{x}$ is the function $g(x) = \sqrt{x}$ reflected over the x-axis and vertically stretched by a factor of 3.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, from $g(x) = \sqrt{3}$ to $f(x) = -3\sqrt{x}$ , g(x) was multiplied by -3, that is, it was reflected over the x-axis(due to the multiplication by the negative number) and vertically stretched by a factor of 3.
