Shawn uses the same amount of mouthwash each day. The table shows the proportional relationship between the amount of mouthwash he uses and time in days. What is the constant of proportionality for the relatyof teaspoons of mouthwash to time in weeks? Show your work. Options:
5
7
35
42

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

answer is x<

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

answer is 33
