The y intercept would be 0 because slope form is
y = mx + b, and this equation has no "b"

When x = 0, y = 1.5 * 0 = 0

Brandon earns a rebate each month on his meals and movie tickets. He earns $0.50 for each movie ticket and $2 for each meal. Las

AURORKA [14]

Let ticket be x and meal be y

So $0.50 for each movie ticket = 0.50x

$2 for each meal = 2y

He purchased 22 tickets, so x = 22

0.50 * 22 = $ 11

Now the total value is $25 (with both ticket and meal)

total = t

0.50x + 2y = t

you know x = 22 and t = 25

11 + 2y = 25

Part A)

2y = 25 -11

y = 14/2

y = 7

Number of meal is 7

Part B)

(don't know about part B)

0.50x + 2y = 25

0.50(22) + 2(7) = 25

11 + 14 = 25

25 = 25

At the city museum, child admission is $6.20 and adult admission is $9.50. On Friday, tickets were sold for a total sales of $10

Nostrana [21]

Answer:

98child tickets were sold that day

Step by step Explanation:

Let the number of children= A of the number of adult

Then

6.20C + 9.50A = 1082.0

From the question it was said that four times as many adult tickets as child tickets were sold which implies that number of adult was FOUR times the children, then we can say

A= 4C

Then substitute into the above equation

6.20C + 9.50A = 1082.0

6.20C + 9.50(4C) = 1082.0

6.20C + 38C= 1082.0

44.2C =1082.0

C= 24.48

But we know that

A= 4C

A=4* 24.48

A= 97.9

Therefore ,98child tickets were sold that day

1) UN MOVIL A SE MUEVE DESDE UN PUNTO CON VELOCIDAD CONSTANTE DE 20m/s EN EL MISMO INSTANTE A UNA DISTANCIA DE 1200m, OTRO MOVIL

alisha [4.7K]

Answer:

El móvil B necesita 60 segundos para alcanzar al móvil A y le alcanza una distancia de 2400 metros con respecto al punto de referencia.

Step-by-step explanation:

Supóngase que cada movil viaja en el mismo plano y que el móvil B se localiza inicialmente en la posición $x = 0\,m$ , mientras que el móvil A se encuentra en la posición $x = 1200\,m$ . Ambos móviles viajan a rapidez constante. Si el móvil B alcanza al móvil A después de cierto tiempo, el sistema de ecuaciones cinemáticas es el siguiente:

Móvil A

$x_{A} = 1200\,m+\left(20\,\frac{m}{s} \right)\cdot t$

Móvil B

$x_{B} = \left(40\,\frac{m}{s} \right)\cdot t$

Donde:

$x_{A}$ , $x_{B}$ - Posiciones finales de cada móvil, medidas en metros.

$t$ - Tiempo, medido en segundos.

Si $x_{A} = x_{B}$ , el tiempo requerido por el móvil B para alcanzar al móvil A es:

$1200\,m+\left(20\,\frac{m}{s} \right)\cdot t = \left(40\,\frac{m}{s} \right)t$

$1200\,m = \left(20\,\frac{m}{s} \right)\cdot t$

$t = \frac{1200\,m}{20\,\frac{m}{s} }$

$t = 60\,s$

El móvil B necesita 60 segundos para alcanzar al móvil A.

Ahora, la distancia se obtiene por sustitución directa en cualquiera de las ecuaciones cinemáticas:

$x_{B} = \left(40\,\frac{m}{s} \right)\cdot (60\,s)$

$x_{B} = 2400\,m$

El móvil B alcanza al móvil A a una distancia de 2400 metros con respecto al punto de referencia.
