Answer:

3x - 6

Step-by-step explanation:

To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)

f(2x) = 3(2x) - 2 = 6x - 2

f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4

Thus

f(2x) - f(x + 2)

= 6x - 2 - (3x + 4)

= 6x - 2 - 3x - 4

= 3x - 6

Rose writes down all of her math quiz scores. Her math scores are 98,78,84, and 96. What is the mean of her math quiz scores?

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Hi, there to find the mean

you need add the numbers and count how many numbers are there and divide

In this case 98+78+84+96= 356

Now we will count

there are 4 numbers

$\frac{356}{4}$ = 89

Your mean will be 89

If you ever have trouble with mean remember this

Mean $\frac{SumofDataPoints}{NumberofDataPoints }$

well it is supposed to be:

Sum of Data Points/Number of Data Points

A submarine is at 756 feet below sea level. How many feet will it need to rise to be at the surface?

makkiz [27]

I think it needs to rise 756 feet since 756 feet below sea level can be thought of as -756 feet above sea level and the serface is 0 feet above sea level. -756feet+756feet=0feet
