Question

What is an estimate of the solution of the equation 6n + 3 = 2? Use a table.

Answer 1

I'm soooooooooooo stuck, can anybody help? Its really confusing

Answer 2

ok make a chart of x and y values

Answer 3

Okay,

Answer 4

n y (y being in place of 2)
1
2
3
4

Answer 5

and plug it in to see what you get

Answer 6

whichever answer is closest to 2 would be a good estimate, if it is between 2 numbers you can add a fraction if you feel like it but I would just choose the number closest

Answer 7

actually you should add negatives too
n y
-1
0
1
2
3

Answer 8

if you did it right it should be somewhere between -1 and 0, closer to 0

Answer 9

okay

Answer 10

when I added 3 to -1 I got 2

Answer 11

but you have to multiply it by 6 first

Answer 12

because it is 6n +3 = 2

Answer 13

But when I work out the problem 6-1 + 3 = 2 it messes up ;_;

Answer 14

ok look ignore the 2
look at the table first, then when you complete the table, compare the y values to 2

Answer 15

okay

Answer 16

the exact answer is (-1/6) so your estimate should be close to that

Answer 17

Thats a fraction correct or is that a division problem?

Answer 18

the fraction is correct, but it is the exact answer, the question is asking for an estimate right?
So either 0 or -1 would be okay estimates

Answer 19

-0.2or -0.1 if you want decimals

Answer 20

It all depends on how your teacher wants it

Answer 21

okay Thanks very much sir I can't tell you how much I appreciate this, I'm usually not bad at this stuff but this one caught me off guard.

Answer 22

no problem
