Which ordered pair is a viable solution if x represents the
number of books he orders and y represents the total
weight of the books, in ounces?
a) (-3,-18)
b) (-0.5, -3)
c) (0,0)
d) (0.5, 3)

The only option (0,0) is possible.

Step-by-step explanation:

Here in options four ordered pairs are given and they are (-3,-18), (-0.5,-3), (0,0) and (0.5,3).

Here, the x-values represent the number of books and the y-value represents the total weight of the books, in ounces.

Now, x must be 0 or a positive integer as it is the number of books.

Hence, the only option (0,0) is possible which means that the weight of zero books is zero. (Answer)

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
