Don has 20 pencile. he buys 3 more packages of pencils that each have 4 in them. howmany pencils does don have now

32 is the answer.

Step-by-step explanation:

First, you multiply 3 X 4 because there are three packages and there are 4 in EACH of them. 3 X 4 = 12. Now you add 12 to 20. 12 + 20 = 32. Hence, that is your answer.

Y as a function of x means y=some wierd formula with only x and numbers in it

y=-3x²-7x-6
yep, wierd formula, check. numbers, check. only x, check

also, if we graph it, there are no vertical ines we can draw that intersect the graph 2 times
basically every x maps to only 1 y
