Answer: {(-8, -14), (-7,-12), (-6,-10), (-5,-8)}

Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

In the relations show here, notice that the first set

of ordered pairs is the only set where each x-coordinate

appears once with a different y-coordinate.

In the other ordered pairs, there is an x-coordinate that appears more

than once and it corresponds to a different y-coordinate.

For example, in the second relation,

the x-coordinate -9 appears twice.

In one case, -9 corresponds to -12 and

in the other case, it corresponds to -8.

So, this is not a function.

<h3>Answer: <u>100 ft</u> is the hypotenuse</h3>

===================================================

Work Shown:

a = 60 and b = 80 are the two known sides

c is the unknown hypotenuse

Applying the pythagorean theorem gets us...

a^2 + b^2 = c^2

60^2 + 80^2 = c^2

3600 + 6400 = c^2

10,000 = c^2

c^2 = 10,000

c = sqrt(10,000)

c = 100

A quick way to see that 100 ft is the missing side is to note that a 6,8,10 right triangle scales up to 60,80,100 after multiplying all three sides by 10.

Or you could start with a 3,4,5 right triangle and multiply all three sides by 20.

<h2>Hello!</h2>

The answers are:

3. Addition property of equality

4. $6x-7+7=12+7$ - Simplification

7. $x=\frac{19}{6}$

To solve the problem, we need to start with the result of the second step:

$6x-7=12$

So,

For the step 3:

Then, for the 3rd step, we have to apply the addition property of equality.

The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.

Then, applying the property, we have:

$6x-7=12$

Adding 7 to both sides, we have:

$6x-7+7=12+7$

For the step 4:

Now, for the 4th step, we have to simplify the expression:

$6x-7+7=12+7$

Then, simplifying, we have:

$6x=19$
