Which statement about solving inequalities is true?
O Adding the same value to both sides of an inequality does not change the solution set.
O Subtracting the same value from both sides of an inequality changes the solution set.
O When dividing both sides of an inequality by the same positive value, it is necessary to reverse the inequality sign.
O When multiplying both sides of an inequality by the same negative value, it is not necessary to reverse the
inequality sign.

When dividing both sides of an inequality by the same positive value, it is necessary to reverse the inequality sign.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
