Answer:

f(8) - f(5) = 9

Step-by-step explanation:

So our function is:

f(x) = 3x - 2

Therefore, f(8) becomes:

f(8) = 3(8) - 2 = 24 - 2 = 22

And f(5) is:

f(5) = 3(5) - 2 = 15 - 2 = 13

Finaly, f(8) - f(5) is therefore:

22 - 13 = 9

So f(8) - f(5) = 9

Hope this helps!

Answer: 6.00 + 3.60x

Step-by-step explanation:

Regular coffee= 2.00 each

Letters= 3.50 each

Samantha buys 3 regular coffees and x letters.

To get the total amount she spends at the coffee shop, we multiply each quantity bought by the price. Therefore, total amount will be:

= (2.00×3) + (3.50×x)

= 6.00 + 3.50x

The expression for the amount spent at the coffee shop is 6.00+3.50x

Answer:

The the exact circumference of a circle with the given radius is 200.96.

Step-by-step explanation:

Here, the radius of the given circle = 32 cm

The, Circumference of a Circle = 2 π r

So, here C = 2 x 3.14 x 32 (taking π = 3.14)

or C = 200.96

Hence, the the exact circumference of a circle with the given radius is 200.96.
