The weight limit of an elevator is 2,200 pounds. michelle is solving an inequality to determine how many 40-pound boxes she can safely bring in the elevator with her if she weighs 110 pounds and has a 10-pound push cart. when the solution to the inequality is graphed on a number line, which statements best describe the graph? check all that apply. there is a closed circle on 55. there is a closed circle on 52. the solution set contains the point 51. the arrow points to the right. the arrow points to the left.

is  B* C* E*

  A. There is a closed circle on 55.

~ B. There is a closed circle on 52.

~ C .The solution set contains the point 51.

  D. The arrow points to the right.  

~ E. The arrow points to the left.

Step-by-step explanation:

Solving the inequality for the number of boxes Michelle can take into the elevator:

so the solution set is x<=52 with a closed circle on 52.

The following are the applicable choices from your  list (all at the same true):

"There is a closed circle on 52"

"The solution set contains the point 51"

"The arrow points to the left"

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.
