HELP IM USING ALL MY POINTS Every day, Krysta's burrito stand uses 1 7/10 bags of tortillas. How many days will 8 1/2 bags of tortillas last?

Write your answer as a fraction or as a whole or mixed number.

5 days

Step-by-step explanation:

If you write it out it will look like this 8 1/2÷1 7/10

since you can't divide mixed fractions very easily, you make them improper fractions. 8 1/2 -> 17/2    1 7/10 -> 17/10

So it looks like 17/2÷17/10

because of maths you have to turn 17/10 into 10/17

And when you do the maths (multiply it together) you get 5

5 days

Step-by-step explanation

1.turn 8 1/2 back to its original form which is 17/2

2. multiply by 5 because 2 times 5 is 10 which is the number we need the make the denominators even and because we multiplied by 5 on the bottom we multipliy by 5 on the top to make it even which is 85/10

3. put 1 7/10 back to its original form which is 17/10, and because 85 divided by 17 is 5 your answer would be 5 days

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.
