Answer:

la alianza: 225

la alternativa: 180

blanco: 405

Step-by-step explanation:

El número total de personas en la ciudad es 810

La fracción de personas que eligieron la alianza es \dfrac{5}{18}

La cantidad de personas que eligieron la alianza es \dfrac{5}{18}\times 810=225

La fracción de personas que eligieron la alternativa es \dfrac{2}{9}

La cantidad de personas que eligieron la alternativa es \dfrac{2}{9}\times 810=180

El número de personas que eligieron el espacio en blanco fue 810-(225+180)=405.

Which of the following is true for the relation f(x) = x2 + 8? Only the inverse is a function. Both the equation and its inverse
Alchen [17]

<u>ANSWER</u>

Only the equation is a function

<u>EXPLANATION</u>

f(x)=x^2+8 is graphed above with its inverse f^{-1}(x)=\pm \sqrt{x-8}.


We perform the vertical line test for both the equation and its inverse.


The equation f(x)=x^2+8 passed the vertical line hence it is a function.

However, f^{-1}(x)=\pm \sqrt{x-8} failed the vertical line test, hence it is not a function.

Vicky ran 5⁄14 of a mile and walked 1⁄7 of a mile. how much further did vicky run than walk?
raketka [301]
To solve, we need to subtract from these two fractions. In order to do this, we will change one of them to have the same denominator as the other.

We have 5/14 and 1/7
Let us change 1/7

Multiply 2/2 (a form of 1 so it does not change the value of the fraction)

2/2 • 1/7 = 2/14

Now subtract from 5/14
5/14 - 2/14 = 3/14

ANSWER: Vicky ran 3/14 of a mile more

Math Plz Help. <br><br>Please graph with two points! <br>explain how you found your answer
Softa [21]
X intercept: y = 0
y= -3/4x -4
0 = -3/4 x - 4
4= -3/4 x
4 • -4/3 = x
-5.3 = x
y intercept: x = 0
y = -3/4 x -4
y = -3/4 (0) -4
y = -4
the points are (-5.3, 0) and (0, -4)
