Answer:
Option b - Subtract
Step-by-step explanation:
Given : Expression 
To find : Which operation should be completed first in the expression below?
Solution :
P - Parentheses
E - Exponent
D - Divide
M - Multiplication
A - Addition
S - Subtraction
In the first step we solve the bracket in the expression 
So, we do subtraction i.e. 12-8=4
Therefore, option b is correct.
Step-by-step explanation:
The slope of the line is -4/7.
Answer:
13 + 5 + 37
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
The function with the smallest rate of change is B.
Rate of change is like slope, the vertical change over the horizontal change.
The horizontal change for each of these choices will be ONE since 3-2 = 1.
Plug 2 in for x to find y, then plug 3 in for x and find y. Subtract the y values and you will get the rate of change as follows:
A) 30
B) 7
C) 192
D) 12
