A.) The median player salary for the New York Yankees was $1.5 million in 2007 and $1.7 million in 2013. Write a linear equation
egoroff_w [7]

A general linear equation is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

Here we will find that the linear equation that represents the situation is

y = 0.033*x + 1.269

And we can expect that the median salary in 2048 is $2.853 million

If the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

a = \frac{y_2 - y_1}{x_2 - x_1}

Here we know that:

in 2007 (x = 7) the median player salary was y = $1.5 million

in 2013 (x = 13) the median player salary was y = $1.7 million.

Then we have two points that we can write as:

(7, 1.5)

(13, 1.7)

Note that the y-value is in millions.

Then the slope of the linear equation will be:

a = \frac{1.7 - 1.5}{13 - 7} = 0.033

So the linear equation is something like:

y = 0.033*x + b

To find the value of b, remember the point (7, 1.5), this means that when we have x = 7, we also have y = 1.5, then we can replace these in the above equation:

1.5 = 0.033*7 + b\\\\1.5 - 0.033*7 = b = 1.269

Then the linear equation is:

y = 0.033*x + 1.269

b) Now we want to predict the median salary in 2048. For 2048 the x-value is x = 48

So we just need to evaluate this in the linear equation:

y = 0.033*48 + 1.269 = 2.853

Then the median salary in 2048 will be $2.853 million

Answer:

c. m∠2 = m∠5

Step-by-step explanation:

We can check 1 by 1 and find the false one.

For answer A, measures 2 and 4 are vertical angles, which means they are equal, so that's not false.

For answer b, measures 4 and 8 are corresponding angles, since X and Y are parallel, so that's also not false.

For answer c, measures 2 and 5 are supplementary to each other, and since the transversal is not perpendicular to X nor Y, they are not equal, therefore, this is false, making that the answer.

For answer d, measure 2 and 6 are corresponding angles, so that's also not false.

Therefore, the answer must be c.
