Answer:
Option A, B, and D are true.
Explanation:
A coefficient is the number that is being multiplied by a variable. For example, in 7b, 7 would be the coefficient.
Terms are the numbers used in the equation. For example, in 3 + 2, 3 and 2 would be the terms.
3n and 5m are not coefficients as there are variables included. 3n and 5m are examples of a variable.
A constant is a number that is not multiplied by a variable. For example, in 8x + 3 + 2b, 3 would be the constant.

Answer:
y = -x +2
Step-by-step explanation:
The slope can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (6 -5)/(-4 -(-3)) = 1/-1 = -1
The y-intercept can be found from ...
b = y -mx
b = 5 -(-1)(-3) = 2
The slope-intercept equation for the line is ...
y = mx +b
y = -x +2 . . . . use the values of m and b we found

Answers
So, the domain is {3, 5, 7, 8}

5y-8(5y+2)=-(25y+46)
Answers
Multiply so there are no parentheses
5y-40y+16=-25y-46
Add 40y to both sides
5y+16=15y-46
Add 46 to both sides
5y+62=15y
Subtract 5y from both sides
62=10y
Divide both sides by 10

Why are there certain question where you multiply to a power and some you don't. Like tree diagrams. This is for probability of compound events.
Answers
Compound probabilities that required AND use multiplication
How to determine the reason?The probability of compound events is of two types
The one that require ANDThe one that require ORAs a general rule, the AND probability require products
Take for instance
P(A and B) = P(A) and P(B)
This gives
P(A and B) = P(A) * P(B)
