Answer:

f(2) = - 1 and f(4) = 3

Step-by-step explanation:

To evaluate f(2), substitute x = 2 into f(x), that is

f(2) = 2(2) - 5 = 4 - 5 = - 1

To evaluate f(4), substitute x = 4 into f(x)

f(4) = - 3(4) + 15 = - 12 + 15 = 3

Pi x 36 - 16<br> Need help on this please answer appropriate.
Bad White [126]

Answer:

To do this question, we must first convert Pi to a decimal form, as shown below:

Pi = 3.14

So then our equation becomes:

3.14 x 36 - 16

We still need to remember PEMDAS.

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

So according to PEMDAS, we need to do 3.14 x 36, which equals 113.04

Now we have to do:

113.04 - 16 = 97.04

Our answer is 97.04
