To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple x - values
A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.
B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3
C. isn't because the x - value 2 has two values. Again, that makes this invalid.
D. is invalid because there is two x - values for 2.
Therefore, the answer is B.
64 of them because 2 inch cubes are needed to completely fill a cubic box of edges 8 inches

Answer:
Jada is moving faster
Jade goes 10 miles in one hour
Han goes 2.5 miles in one hour
Step-by-step explanation:
Jada is 2miles/12 minutes=2(5) miles in 12(5) minutes
Jade goes 10 miles in 60 minutes (or one hour)
Han is 1 mile/24 minutes=1(2.5) miles in 24(2.5) minutes
Han goes 2.5 miles in 60 minutes (or one hour)
Jada is moving faster
Step-by-step explanation:
Set up a proportion:
26.5/x = 17/58
Cross multiply and you get:
17x = 1537
x = 90.4
So the measure of PQ is 90.4
Thats when point =0. equation of a line mx +b where m is the slope
and b is the intercept
