The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. the cost of one battery is $0.75. the toy itself costs $12. which equation represents the situation?

y = 12 + 0.75 x

Step-by-step explanation:

Here, x represents the number of batteries used for a toy and y represents total estimated total cost,

Since, the cost of a toy = $ 12,

And, the cost of one battery = $ 0.75,

⇒ The cost of x batteries = 0.75 x dollars,

Since, total cost =  the cost of the toy + the cost of x batteries

⇒ y = 12 + 0.75 x

Which is the required equation that represents the given situation.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
