Answer:

A.) 4h : $36

Step-by-step explanation:

Why it's right: they equal the same thing

5/45 = 1/9

4/36 = 1/9

Why it's wrong: similar, but backwards

54/6 = 9

Just plain wrong:

4/50 = 2/25

63/9 = 7

Choose the solution set represented by the following graph.
olga55 [171]

Answer:

The solution set represented by the following graph is:

                {x | x∈ R, x < -2}

Step-by-step explanation:

Clearly from the figure we could see that the solution set is to the left of ' -2' and excluding the point '-2' since there is a open circle at -2.

This means that -2 is not included in the set.

Also in interval; form the set of points that belong to the solution set are:

                      (-∞,-2)

in set-builder form it is written as:

                      {x | x∈ R, x < -2}
