Let x = adult tickets
Let y = children's tickets

x + y = 800
8x + 4y = 4,400

From the first eq, x = 800 - y, plug this in to the second eq
8(800-y) + 4y = 4,400
6400 - 8y + 4y = 4,400
2000 = 4y
500 = y

x = 800 - 500
x = 300

300 adult tickets were sold.

If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y ?
Reika [66]

Answer:

10

Step-by-step explanation:

2x - 3y = 24 ------ (1)

3x + 4y = 2 ------ (2)

(1) × 4,

8x - 12y = 96 ------ (3)

(2) × 3,

9x + 12y = 6 ------ (4)

(3) + (4)

17x = 96 + 6

= 102

x = 102 ÷ 17

= 6

Sub x = 6 into (2),

3(6) + 4y = 2

18 + 4y = 2

4y = 2 - 18

= -16

y = -16 ÷ 4

= -4

Therefore,

x - y = 6 - (-4)

= 6 + 4

= 10

Which of the following function is graphed?
Thepotemich [5.8K]

Answer:

D

Step-by-step explanation:

Try to remember this formula.

y=a|b(x-c)|+d

Where a is the vertical multiplier, b is the horizontal multiplier, c is the x coordinate of the vertex, and d is the y coordinate of the vertex.

Since the vertex on the graph is (2,3), c and d have to be 2 and 3.

Also, there are no vertical/horizontal stretches so the a and b values stay at 1.

The final equation would come out to y=|x-2|+3

Which table has a constant of proportionality between y and x of 1.5
Cerrena [4.2K]

Answer:

C

Step-by-step explanation:

In a proportional relationship the constant of proportionality k is

k = \frac{y}{x}

Check this ratio for each of the values

A

\frac{7.5}{5} = 1.5 , \frac{19.5}{13} = 1.5 , \frac{33}{23} = 1.4347.... ← Thus not A

B

\frac{9.5}{8} = 1.1875 ← Thus not B

C

\frac{12}{8} = 1.5 , \frac{13.5}{9} = 1.5 , \frac{27}{18} = 1.5

Thus the table with k = 1.5 is Table C
