12. Marilyn, Sharon, and Rhonda collect earrings. Marilyn has one-half as many earrings as Sharon. Rhonda has 15 more earrings than Marilyn. Let x represent the number of earrings that Sharon has Which algebraic expression represents the number of earrings Rhonda has?

R= 1/2S + 15

Step-by-step explanation:

R=Rhonda's earrings

S= Sharon's earrings

Marilyn has 1/2 as many earrings as Sharon, so in order to find how many earrings Marilyn has, you must divide Sharon's amount by 2. Hence the 1/2S.

Rhonda has 15 more earrings than Marilyn, so if you take the quantity of Marilyn's earrings (1/2S) and add 15 to it, you should get your answer.

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

answer: the answer is 23
