How to find if it is a function or not:
The set of ordered pairs (Z,A) where z is the zip code, and A is the street address.​

Answers

Answer 1

Answer: It is not a function.

Step-by-step explanation:

A function is something that "eats" an input and transforms it into an output.

We write them as y = f(x)

Where x is the input, and y is the output.

Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.

This means that, for example, if we have, for x = x1.

And a single

f(x1) = y1

f(x1) = y2

where y1 and y2 are different values.

Then this is not a function, because it is mapping the value x1 into two different outputs.

In this case, we would have:

f(Z) = A.

So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.

This means taht the set (Z, A) can not represent a function.

3x+3y=180 what is the answer to this problem

Answers

Answer:

If you are solving the equation for x :

3x + 3y = 180

3x = -3y + 180

x = -y + 60 or x = 60 - y

If you are solving the equation for y:

3x + 3y = 180

3y = -3x + 180

y = -x + 60 or y = 60 - x

702 can not be written as the product of 2 prime numbers, because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore 702 is a prime number.

Write an expression to represent the perimeter of the triangle below in simplest form

Answers

Answer:

Perimeter of the given triangle = [tex]\frac{7x+38}{(x+8)(x+5)}[/tex] units

Step-by-step explanation:

Perimeter of a polygon = Sum of the measures of all sides of the polygon

From the picture attached,

Perimeter of the given isosceles triangle = Measures of two equal sides + remaining side

P = [tex]2(\frac{3}{x+8})+\frac{x}{x+5}[/tex]

  = [tex]\frac{6}{(x+8)}+\frac{x}{(x+5)}[/tex]

  = [tex]\frac{6(x+5)+(x+8)}{(x+8)(x+5)}[/tex]

  = [tex]\frac{6x+30+x+8}{(x+8)(x+5)}[/tex]

  = [tex]\frac{7x+38}{(x+8)(x+5)}[/tex] units

Therefore, perimeter of the given triangle is [tex]\frac{7x+38}{(x+8)(x+5)}[/tex] units

Shivani started the week with $9,000 in her bank account. Then she spent $5,000 on an antique clock. Which integer represents the final balance of the bank account?

Answers

Answer:

4,000 is the integer representing the final balance of the bank account

Step-by-step explanation:

Here, we are told that Shiavni had a total of $9,000 in her bank account at the start of the week of which she spent $5,000 out of it on an antique clock.

Now, we want to know the integer that represents the amount which is the final balance of the bank account.

Mathematically, when we talk of an integer, we are simply referring to a whole number, be it negative or positive.

Thus, the integer is the case is the difference in what she had at the beginning of the week minus the cost of the clock

That would be; $9,000 -$5000 = $4,000

Please help Factor the expression using the GCF the expression 32z-48 factored using the GCF is

Answers

Answer:

16(2z -3)

Step-by-step explanation:

There are two ways of solving this problem.

List out the factors of the numbers:

32z - 48

= 32 * z - 48

32= 1, 2, 4, 8, 16, 32

48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

the largest common factor that both numbers have in common is 16,

So factoring the equations means the one has to divide the equation by 16 and write it outside of the parenthesis.

16 * ( 2 * z - 3)

16(2z -3)

Another way of solving the problem:

prime factorize the number:

32 = 2^5

48 = 2^4 * 3

Both numbers have 2^4 as their largest factor in common meaning that that is their GCF. 2^4 is 16.

Now factor out 16 and write it on the outside of the parenthesis.

16 * ( 2 * z - 3)

16(2z -3)

Answer:

16(2z -3)
