The table shows values that represent a quadratic function
Mamont248 [21]

Answer:

- 8

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 3, 5 ]

From the table

f(b) = f(5) = - 26

f(a) = f(3) = - 10

Hence

average rate of change = \frac{-26-(-10)}{5-3} = \frac{-16}{2} = - 8

How are adjacent angles and vertical angles alike? Please help me.
vekshin1

Vertical angles are angles that are the same (for example >< since they're the same). Adjacent angles are angles that share a side with another angles, such as \|, since they are sharing on angle that connects the two.

Now that you know what each is, you can tell that they are similar because <em>they both have something in common</em>. When dealing with vertical angles, you can tell that they are the same thing, meaning they each share the whole shape of the angle. Adjacent angles share one whole line together; therefore, showing you that both have a line in common.

           adjacent angle              A        <em>they both share angle A.</em>

                                                   |

A student said that the y-intercept of the function y = 3 · 4x is 4. What is their mistake? What is the actual y-intercept?
patriot [66]

Answer:

<h2>The y intercept is 0</h2>

Step-by-step explanation:

the equation of a line is given as

y= mx+c

where

m= is the slope

c= is the y intercept

their mistake is that they did not recall that if the "c" is not shown, it is assumed to be zero (0)

Dan was thinking of a number. Dan subtracts 2.6 from the number and gets an answer of 72.8. Form an equation with
nirvana33 [79]

Answer: x - 2.6 = 72.8

x is the number which Dan was thinking (x > 2.6)

we have:

x - 2.6 = 72.8
