Anna wants to celebrate her birthday by eating pizza with her friends. For $42.50 total, they can buy p boxes of pizza. Each box of pizza costs $8.50.

Answer:

If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.

For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats

a function because no x value is repeating the x value is known as an independent value. Does that make sense?

"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."

If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.

For a relation to be called a function, the following holds true:

Each x-value (input) has it's own unique y-value (output).

A x-value cannot give two different y-values.

If an x-value repeats, the corresponding y-value must repeat.

Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.

Answer:

Step-by-step explanation:

The problem here is that the question is not clear.  In particular, what does "2)" mean?

Reflecting across the x axis is easy.  Think of the x axis as a mirror.  when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror.  So, to reflect across the x axis, just multiply all the y values of the points by -1.  For the reflection part

(-3,4) becomes (-3,-4)

(1,2) becomes (1,-2)

(-2,1) becomes (-2,-1)

Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.

If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.

Answer:

x=6

Step-by-step explanation:

I would look at this triangle and notice that x can be solved by setting up a ratio.

I generally put the short side of the triangle on the top and the long side on the bottom

4/x = x/9

You then cross multiply to get 36=x^2, or +-6=x

A length of a triangle cannot be negative, so we are left with the answer x=6

$532

Step-by-step explanation:

Hey There!

So to solve this problem the first thing that we want to do is find the cost of 1 ball

To do so we divide the total cost of 10 balls by 10

280/10=28 so each ball cost 28

now to find the cost of 19 balls we multiply the cost of 1 ball by 19

18x28=532

thus meaning 19 balls cost $532

Answer:

$532

Step-by-step explanation:

We need to find the cost of 1 ball and then multiply it by 19, here is the math:

280/10=28

Now we know that 28 is the cost of 1 ball.

28 x 19=532

The cost of 19 balls is $532

The answer is 12 − 10

Step-by-step explanation:

step 1. 0.12 = 12/100 (by definition)

step 2. 12/100 = 6/50 =3/25.

Step-by-step explanation:

step 1. a^2b^2 = (0.3)^2(0.9)^2

step 2. = (0.3)(0.3)(0.9)(0.9)

step 3. = 0.0729

The value of the expression a²b² is 0.0729.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The value of a and b are,

a = 0.3 and b = 0.9

Now, The expression is;

⇒ a²b²

Substitute values of a and b we get;

⇒ a²b² = (0.3)² × (0.9)²

           = 0.09 × 0.81

           = 0.0729

Thus, The value of the expression a²b² is 0.0729.

The percentage of students who used Snap the most is given as:

= 44%

Step-by-step explanation:

a) Data and Calculations:

App   Number of Students

Face          8

Snap        22

Insta        20

Total      50

The percentage of Snap users = Number of Snap users/Total users * 100

= 22/50 * 100 = 44%

b) This represents the proportion of all the students surveyed about the use of social media app.  Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap.  This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.
