En un aeropuerto dos aviones A1 y A1 se acercan para aterrizar, si la ecuación de la trayectoria del primero es -x+2y-100=0, mie

liraira [26]

No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.

-------------------------

La trayectoria del primero es:

$-x + 2y - 100 = 0$

$x_1 = 2y - 100$

Para el segundo, tiene-se que:

$-x + 200 + 2y = 0$

$x_2 = 2y + 200$

Igualando los valores de x:

$x_1 = x_2$

$2y - 100 = 2y + 200$

$0y = 300$

No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.

A weed called the raindrop vine is known for growing at a very fast rate. It can grow up to 0.75 feet per day. How fast in inche

jarptica [38.1K]

1 foot = 12 inches.

0.75 feet x 12 inches per foot = 9 inches per day.

1 day = 24 hours.

9 inches / 24 hours = 0.375 inches per hour ( 3/8 inch per hour)

Not sure if you need a decimal or fraction for an answer so I provided both.

Find the value of x<br> A. 8 <br> B. 4<br> C. 19<br> D. 24

<h3>Hello There!!</h3>

Given figure is a <u>parallelogram</u>

Value of"x"

<h3><u>Solution</u></h3>

$m \angle \: A = m \angle \: C$

$2x + 35 = 5x - 22$

$\implies 2x - 5x = - 22 - 35 \div \\ \implies - 3x = - 57 \\ \\ \implies x = \frac{ - 57}{ - 3} \\ \\ \implies x = \cancel\frac{ - 57}{ - 3} \\ \\ \implies x = 19$

$\therefore \text{Option C= 19 is the correct answer}$

<h3>Hope this helps</h3>
