Answer 1

do not delete questions that have answers please

Answer 2

ok

Answer 3

its rude to those who gave answers, its rude to those who could have used it to study by, and its just plain rude in general ... thnx

Answer 4

np

Answer 5

A linear equation like
y=ax, here
\[\frac{y}{x}=a\]
so y and x are in the ratio a:1 Can you tell what's the answer

Answer 6

i was working up a matrix to get the coeffs of that last one to test a quadratic to:

y = 13/2 x^2 + 31/2 x + 11

but i aint got the other points to test it with ....

Answer 7

i can give them to u

Answer 8

id appreciate it, just so i can have some closure with it lol

Answer 9

lol ok one sec

Answer 10

(–3, 18), (–2, 6), (–1, 2), (0, 11), and (1, 27)

Answer 11

http://www.wolframalpha.com/input/?i=y+%3D+13%2F2+x%5E2+%2B+31%2F2+x+%2B+11%2Cx%3D-3

when x=-3, y=23;

when x=1, y=33

but the other 3 fit to the quadratic

Answer 12

so, even tho it appears in a u shape; and it might be best fit as a quadratic, it is not a perfect fit

Answer 13

the end :)

Answer 14

haha thx :)
