What is the coefficient in the expression 4x + 2
O2
O4
Ox
O+
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

hope it helps

how to find slope of line???
please help!!!
Answer: -1
Step-by-step explanation:
Find the two coordinates first.
In this case, they are (-4, 1) and (-2, -1).
Use the following formula to calculate slope:
[tex]\frac{y2-y1}{x2-x1}[/tex]
Substitute in the coordinates:
[tex]\frac{1-(-1)}{-4-(-2)}[/tex] = [tex]\frac{2}{-2}[/tex] = -1

Mimi has 9/10 of a punnet of strawberries. Jamie has
four times as many strawberries as Mimi. How many
punnets of strawberries does Jamie have?
Give your answer as an improper fraction in its
simplest form.
Answer:
36/10 (improper fraction)
3 3/5 of a punnet of strawberries(mixed Number)
Step-by-step explanation:
Mimi = 9/10 of a punnet of strawberries
Jamie has four times as many strawberries as Mimi
Jamie = 9/10 × 4
= (9×4) / 10
= 36/10
= 3 6/10
= 3 3/5 of a punnet of strawberries
Jamie = 3 2/5 of a punnet of strawberries

Annie was going to use the elimination method. She was ready to add the same value to both sides of the equation to eliminate the x-terms when she noticed a problem: Both x-terms are positive!
2x+7y=13
2x+3y=5
Rather than adding the equations together, how else could you eliminate the x-term? Once you have figured out a method, solve the system and check your solution.
