Answer:

A. 8/7

Step-by-step explanation:

<h3>Step 1     </h3>

4/7 - (-4/7) --> 4/7 + 4/7

The two minutes turn into a plus, removing the bracket.

<h3>Step 2</h3>

4/7 + 4/7 = 8/7

Add the two fractions together.

The table represents a function. A 2-column table with 5 rows. The first column is labeled x with entries negative 6, 7, 4, 3, n
sveta [45]

Answer:

-2 is an output of the function.

Step-by-step explanation:

The given table is as follows:

\left[\begin{array}{cc}{x}&f(x)\\-6&8\\7&3\\4&-5\\3&-2\\-5&12\end{array}\right]

Here, the values written on the left side of table i.e. values of x are known as the <em>domain </em>values or <em>input </em>values to a function.

The values written on the right side of table i.e. values of f(x) are known as the <em>range</em> values or <em>output</em> values of the function f(x).

Let us consider the pairs of values:

(-6,8) then left side value is of x and right side value is of f(x)

i.e. when x=-6, the output value f(x) =8.

The same thing applies for all the pairs of values.

similarly for the pair (3,-2):

Left side value is of x and right side value is of f(x)

i.e. when x=3, the output value f(x) =-2.

So, the answer is:

<em>-2 is an output of the function.</em>

Find the length of the diagonal BD in the quadrilateral ABCD shown in the coordinate plane ?
Leno4ka [110]

bearing in mind B is at (4,3) and D is at (-2,-4).


\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{4}~,~\stackrel{y_1}{3})\qquad D(\stackrel{x_2}{-2}~,~\stackrel{y_2}{-4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BD=\sqrt{(-2-4)^2+(-4-3)^2}\implies BD=\sqrt{(-6)^2+(-7)^2} \\\\\\ BD=\sqrt{36+49}\implies BD=\sqrt{85}
