Alejandro loves to go to the movies .He goes both at night and during the he day
.The cost of a matinee is $7 .The cost of an evening show is 12 .Alejandro went to see a total of 6movies and spent $52. Let x represent the number of matinee movies attended and y represent

the number of evening show movies attended.

The number of matinee movies attended is 4.

The number of a evening show movies attended is 2.

Step-by-step explanation:

Therefore, from the given data the equation can be framed as :

⇒ x + y = 6  (1)

Therefore, from the given data the equation can be framed as :

⇒ 7x + `12y = 52  (2)

To solve the equations for x and y values :

Mulitply eq (1) and by 7 and subtract eq (2) from eq (1),

  7x + 7y = 42

- (7x + 12y = 52)

      - 5y = - 10

⇒ y = 10/5

⇒ y = 2

The number of a evening show movies attended is 2.

Substitute y=2 in eq (1),

⇒ x+2 = 6

⇒ x = 6-2

⇒ x = 4

The number of matinee movies attended is 4.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
