Question

y=ax^2+c with a graph that includes (0,1/3) (-3, 82?3)

Answer 1

(-3, 82/3)

Answer 2

since \((0,\frac{1}{3})\) is on the graph you know \(c=\frac{1}{3}\) because that is what you get if \(x=0\)

Answer 3

so you have
\[y=ax^2+\frac{1}{3}\] put \(x=-3\) and \(y=\frac{82}{3}\) and solve for \(a\)

Answer 4

in other words, solve
\[\frac{82}{3}=9a+\frac{1}{3}\] for \(a\)

Answer 5

3x^2+1/3

Answer 6

?

Answer 7

@satellite73

Answer 8

@satellite73 help..

Answer 9

a=3

Answer 10

you can deduct 1/3 on both sides of the equation to isolate 9a
show me what you came up with

Answer 11

ok

Answer 12

y=-3x^2+2/3

Answer 13

@nincompoop

Answer 14

this is what satellite left us:
\[\frac{ 82 }{ 3 }=9a+\frac{ 1 }{3 }\]

Answer 15

oh,

Answer 16

deducting 1/3 on both sides of the equation will leave us
81/3 = 9a

now you just have to divide 9 on both sides of the equation so you are left with a

Answer 17

y=3x^2-1/3

Answer 18

@you. can you help meh?

Answer 19

I'm 12 I don't know how to solve this

Answer 20

oh

Answer 21

@selenamalter now just divide 81/3 by 9 to get the value of a

\[\frac{ 81 }{ 3 }\div \frac{ 9 }{ 1 }\]

we know that 9 x 9 is 81. so, 81/9 is 9
and 9/1 = 9
therefore, a = 9

Answer 22

sorry. THEREFORE, a = 9/3

Answer 23

9/3 = 3

Answer 24

okay, so
the full answer would be

Answer 25

those are the answer options
and
D. none of these answers

Answer 26

assuming that where satellite left off is correct, then the answer would be D

I trust satellite's math skills LOL

Answer 27

;)
wow, thanks :D

Answer 28

no problem gal

Answer 29

i can go to bed now lol....
thank ya lad :D

Answer 30

give satellite the medal. I didn't really do anything. I just merely showed you what he wanted you to do.
