To do this I'm going to set up an equation. We don't know how many hamburgers were sold so we will call it x. The number of cheeseburgers sold was two times the number of hamburgers sold so we are going to call the number of cheeseburgers 2x. These add up to 267 so we can make and solve the equation:

x+2x=267

3x=267

x=89

89 hamburgers and 178 cheeseburgers were sold.

A gym initially has 5000 members. Each year, the gym loses 10% of its current members and gains 100 new members. Which recursive
Elis [28]

Answer:

An = A0 + 100 * n - (An-1) * 0.10

Step-by-step explanation:

Tenemos una regla recursiva para una secuencia es una fórmula que nos dice cómo avanzar de un término a otro en una secuencia. Por lo tanto debemos buscar a An.

Hay un valor inicial que es 5000, una ganancia y una perdida de clientes, que podemos representar así:

An = 5000 + Ganancia - Perdida

Inicial = A0 = 5000

Ganancia = 100, pero cómo sucede cada año, sería: 100 * n

Perdida = 10% de los miembros actuales, si al principio son 5000 por lo tanto A0 * 0.10, pero en este primer caso es que es A0, pero en general serían An-1

reemplazando:

An = A0 + 100 * n - (An-1) * 0.10

The art club is designing a rectangular mural for the school hallway. Three
AysviL [449]

Answer:

The coordinates are (50, 103)

Step-by-step explanation:

The three hallways are AB, BC, CD.

The co-ordinate of D is (50, 75).

The school's flagpole is 28 meters right of the point D.

Hence the y-coordinate for the flagpole will be same as D, that is 75.

The x-coordinate will be (28 + 75) = 103.

The location of the school's flagpole will be represented by (50, 103)

If a line contains both point s and the origin, which point would the line also contain?
Ne4ueva [31]
The answer is y = 2x + 0 or y = 2x.

The line passes through (0,0) and (1,2). The slope is

m = (2 − 0)/(1 − 0) = 2.

(You could also see this by drawing the two points and a slope triangle and use the rise/run idea of slope.)

In the slope-intercept form, y = mx + b, you now know that m = 2 and b = 0, so the answer is

y = 2x + 0 or y = 2x.
