A(-10,-3), B(7,14)

slope of AB = (-3-14)/(-10-7) = 1

slope of perpendicular to AB = -1

equation of perpendicular through C(5,12):

y-12 = -(x-5)

y-12 = -x+5

x = -y+17

x-intercept is the value of x when y=0.

ASHA 777 [7]

Answer:

3(x+7)/4

Step-by-step explanation:

Three times the sum of a number and 7 will be 3(x+7) because it is triple the amount of that unknown number plus seven and then after that we divide what we get from 3(x+4) and divide that by 4 which makes the equation 3(x+7)/4.

se vendieron 144 boletos. 2 pesos por adulto y un peso por niño, si se gastaron 207 pesos cuantos boletos de adulto se vendieron

natulia [17]

Answer:

Se vendieron 81 boletos de niños y 63 boletos de adultos.

Step-by-step explanation:

La cantidad de boletos vendidos es igual a:

$144 = a + n$ (1)

En donde a es por adultos y n por niños

A su vez, el dinero gastado equivale:

$207 = 2*a + 1*n$ (2)

Resolviendo la ecuación (1) para a:

$a = 144 - n$ (3)

Introduciendo (3) en la ecuación (2) tenemos:

$207 = 2*(144 - n) + n$

$n = 81$

Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo n en la ecuación (3):

$a = 144 - n = 144 - 81 = 63$

Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.

Espero que te sea de utilidad!
