Helloo everyone can you please help me on this pls

This is the same as writing 6 & 1/2 or 6  1/2

======================================================

Explanation:

Notice that 13/2 = 6.5

So we can have 6 full vials, plus a bit left over. The leftover bit is 0.5 which converts to 1/2

So 6.5 in decimal form converts to the mixed number

This mixed number does not mean 6 times 1/2. It means 6 whole vials plus another 1/2 a vial. The notation is probably a bit confusing. It might be easier to say , but the drawback is now things are a bit clunky.

On a keyboard, we could write as 6 & 1/2 or as 6  1/2. The spacing is important to separate out the whole and fractional parts.

To be perfectly honest, I don't like the notation 6  1/2 because to me it seems too vague, and it might be mistaken for 61/2. I prefer the 6 & 1/2 notation more since it's more descriptive and we wouldn't have a mix-up. But be sure to type in the answer in the format your teacher wants.

the range of a function is the range of y-values for which it is defined, or exists. given that we are only looking at the y-values, we can already discount the first two answers as they deal with the domain of the function (range of x-values).

now, what we need to do is find the smallest and highest y-values for which the function is defined. if you'd like, you could take a ruler and start at the very bottom of the graph, find the lowest point, then move the ruler higher and higher until you reach the highest point. doing so either in your head or with an actual ruler, we can see that the lowest y-value is -5 and the highest y-value is -1.

the question now remains as to whether they are included in the range (fourth answer) or excluded (third answer). the key here is to recognise whether they are marked with an open or a closed circle. since both (-2, -5) and (2, -1) are marked with a closed circle, they are points that exist on the graph and are thus included in the range (note that if they were marked with an open circle like (4, -2) then that would signify that there is a break in the graph at that point).

thus, the fourth answer, (y | -5 ≤ y ≤ -1), is correct.

also note that usually it is good practice to scan your eye inbetween the highest and lowest point for any breaks in the graph - we do have one here at (4, -2), however -2 is still included in the range because there is another point that is included in the graph with the same y-value, ie. point (1, -2).

i hope that but if you require any further explanation don't hesitate to comment below.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
