Just numbers 9,10, and 11

For a school drama performance, student tickets cost $5 each and adult tickets cost $10 each. The sellers collected $3,570 from

Ray Of Light [21]

Answer:

The number of adult tickets sold is a=202\ tickets

The number of student tickets sold is c=310\ tickets

Step-by-step explanation:

c------> the number of student tickets sold

a-----> the number of adult tickets sold

we know that

a+c=512 -----> equation A

5c+10a=3,70-----> equation B

therefore

the solution is

the number of adult tickets sold is a= 202 tickets

the number of student tickets sold is c= 310 tickets

The parent function y = |x| stretched vertically by a factor of 2, shifted left 3 units and down 4 units

OlgaM077 [116]

Hello!

Let's go through some formula to distinguish the changes that happen to a graph's equation when they are transformed.

Vertical shifts have this type of formula:

f(x) + k → up k units and f(x) - k → down k units

Horizontal shifts have this type of formula:

f(x + k) → left k units and f(x - k) → right k units

Reflections have this type of formula:

-f(x) → reflect over x-axis and f(-x) → reflect over y-axis

Vertical stretches have this type of formula:

a · f(x) where a > 1

Vertical compressions have this type of formula:

a · f(x) where a < 1

Horizontal stretches have this type of formula:

f(a · x) where a > 1

Horizontal compressions have this type of formula:

f(a · x) where a < 1

With that in mind, we can write our transformed absolute value function.

Since the equation is vertically stretched by a factor of 2, a = 2.

y = 2|x|

Also, since the function is shifted left 3 units, k = -3.

y = 2|x + 3|

Finally, the function is also shifted down 4 units, so k = -4.

y = 2|x + 3| - 4

Therefore, the equation is y = 2|x + 3| - 4.

What is the slope of the following 12x - y = 30 -12

antiseptic1488 [7]

Answer:

12

Step-by-step explanation:

Rearrange into the form y = mx + c, where m is the slope.

12x - y = 30

y = 12x - 30

m = 12

A fast food chain surveyed a random sample of students to determine what pizza they prefer cheese pizza was preferred by 40 stud

TEA [102]

Answer:

Based on the results 200 of the 340 students can be expected to prefer cheese pizza.

Step-by-step explanation:

Given:

Cheese pizza was preferred by 40 students.

Pepperoni pizza was preferred by 28 students.

Now, based on the results how many students of the 340 can be expected to prefer cheese pizza.

Number of students preferred cheese pizza = 40.

Number of students preferred pepperoni pizza = 28.

Total number of students = 40+28 = 68.

As, 40 out of 68 preferred cheese pizza.

To get the number of the students out of 340 students who preferred cheese pizza based on the results.

Let the students be $x$ who preferred cheese pizza.

So, we set proportion:

40:68 = $x$ : 340.

Now, solving by using cross multiplication method:

$\frac{40}{68} =\frac{x}{340}$

By cross multiplying we get:

$13600=68x$

Dividing both sides by 68 we get:

$200=x\\x=200.$

Therefore, based on the results 200 of the 340 students can be expected to prefer cheese pizza.
