When you are given a function and it asks you what f(a number) is then you plug in the number in the parentheses into everywhere you see x in the function equation.

Essentially this equation is saying that x is equal to 5

f(5)

f(x) = 3x + 2

f(x) = 3(5) + 2 ---> 15 + 2 ---> 17

so...

f(5) = 17

Hope this helped!

Answer:

(-7,4]

Step-by-step explanation:

I'm going to assume that you need this in interval form

The domain is just asking for all the possible x values

The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [

the furthest to the right the line goes is 4 and because the circle is closed it's written with ]

but it all together and get

(-7,4]

Plz Help Me Asap!!!!

Hi there!

To solve this problem, we need to find x, and plug it into measure c to get the value of c.

First, let's find x.

Since we know that the sum of all measures of a triangle is always equal to 180 degrees...

6x + 2x + 2x = 180
10x = 180
x = 18

Now, let's plug it in.

2x
= 2*18
= 36

So, measure c is 36 degrees.

Hope this helps!

1. (section 2.1) Bungee jumping: Jimmy jumped off the Tallahatchie Bridge, 100 ft above
Tems11 [23]

Answer:

18.4 ft per second.

Step-by-step explanation:

Bungee jumped off the Tallahatchie Bridge, which is 100 ft above the water surface.

And after 5 seconds he was at 8 ft above the water surface.

Therefore, in total 5 seconds, he descends by total ( 100 - 8 ) = 92 ft altitude.

Hence, the average rate of change of his altitude is given by  

\frac{\textrm{Total altitude change}}{\textrm{Total time taken}} = \frac{92}{5} =18.4 feet per seconds. (Answer)
