Name the operation the should be done first in this expression: 10 - (3 + 4)

Step-by-step explanation:

To figure this question out, you must follow the rule:

Parenthesis

Exponent

Multiply

Divide

Addition

Subtraction

As you can see, the first operation in PEMDAS is Parenthesis.

Meaning the first thing you do is the numbers in parenthesis

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
