B) is your answer

The cost for x children is $6. This means that the children is a variable (x), but no matter how much children there is, each ticket costs $6 (constant). (becomes 6x)
The cost for y adult is $11. This means that the adults is a variable (y), but no matter how much adult there is, each ticket costs $11 (constant)
(becomes 11y)
So B) is correct.

hope this helps

B.

The cost for x children and y adults to go to the movies if adult tickets are $11 and child tickets are $6.

Example 3 children and 2 adults ( 6(3) + 11(2) )

A set of numbers was created using a rule that states, "Start with 2, multiply by 3." Write the numbers included

WITCHER [35]

2, 6, 18, 54, 162, 486...

Start with the number 2.
$2*3=6 \\ 6*3=18 \\ 18*3=54 \\ 54*3=162 \\ 162*3=486$
And continue with that pattern from there.

Answer:

Point B

Step-by-step explanation:

Lines given:

y= 2/5x - 1/2
y= -1/3x +2/3

x coordinate of intersection of given lines is:

2/5x - 1/2= -1/3x+2/3
2/5x+1/3x= 2/3 +1/2
6/15x+5/15x= 4/6+3/6
11/15x=7/6
x= 7*15/11*6
x= 35/22

For this value of x, the value of y is:

y= 2/5*35/22 - 1/2
y=14/22- 1/2
y= 3/22

As per graph point (35/22, 3/22) is point B

Use the substitution method to solve the system of equations. x+y=11 -x=-y-9

allochka39001 [22]

<h2>Answer:</h2>

Like you said, we need to use substitution to solve for y.

$x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10$

Now that we've solved for y, we can plug in the number we got into one of the original equations. (You can choose either equation, but I will use the first one.)

$x + 10 = 11\\\\x = 1$

Now we have the solution of this system.

$(1, 10)$
