Answer:

input = 5

Step-by-step explanation:

y = -2x - 6

When y = -16

-16 = -2x - 6

divide by -2 on both sides,

8 = x + 3

x = 8 - 3 = 5

Para el diseño de un tanque de tratamiento de agua se determina que su centro está ubicado en la posición (0;14) metros y está r
Andreas93 [3]

Answer:

Diámetro = 8 metros

Step-by-step explanation:

La ecuación de la circunferencia esta en la forma general y para identificar su centro y su radio debemos llevarla a la forma canónica completando cuadrados:

x^{2} +y^{2} -28y + 180= 0

Solo necesitamos completar cuadrados en la variable y, sumando a ambos lados de la ecuación 196, que resulta de dividir 28 entre 2 y elevarlo al cuadrado

x^{2} +y^{2} -28y + 196 = -180 +196

Entonces obtenemos

x^{2} + (y-16)^{2} = 16

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros

A pool had 10 1/2 gallons of water in it Jake and his friend splashed g gallons of water out of the pool. There are 7 7/8 gallon
kolezko [41]

Answer: 6/625 gallons of water wa splashed out of the pool

Step-by-step explanation:

Total number of gallons of water in the pool was 10 1/2. Converting to improper fraction, it becomes

21/2 gallons.

Jake and his friend splashed g gallons of water out of the pool. There are 7 7/8 gallons still left in the pool. Converting 7 7/8 to improper fraction, it becomes

63/8 gallons

This means that

g + 63/8 = 21/2

g = 21/2 - 63/8 = (84 - 63)/8

g = 21/8 = 2.625 gallons

On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, negative 3) and point B is at (negative 4, 9).
zimovet [89]

Answer: (0,1)

Step-by-step explanation:

If (x_1, y_1) and  (x_2, y_2) are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.

Then , the coordinates of (x,y) is given by :-

x=\dfrac{nx_1+mx_2}{m+n}

y=\dfrac{ny_1+my_2}{m+n}

Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).

Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :

x=\dfrac{2(2)+1(-4)}{1+2}=0

y=\dfrac{2(-3)+1(9)}{1+2=1}

Hence, the x- and y- coordinates of point E = (0,1)
