I picked C am i correct?

Answer 2

@Michele_Laino

Answer 3

If not, what is the correct answer, and why? Thanks

Answer 4

we can simplify your function. For example, we can factor out 9 at numerator and 3 at denominator, so we can write this:
\[\Large \frac{{9{x^2} + 9x - 18}}{{3x + 6}} = \frac{{9\left( {{x^2} + x - 2} \right)}}{{3\left( {x + 2} \right)}}\]

Answer 5

okay i get it so far....

Answer 6

can you simplify that expression further?

Answer 7

Need a bit of help

Answer 8

ok! try please

Answer 9

kk doin it now...

Answer 10

we have to factorize the numerator

Answer 11

9 (x-1) (x+2)

Answer 12

in order to do that, we have to find two numbers such that their sum is -1 and their product is -2

Answer 13

can you find them?

Answer 14

9 (x-1) (x+2)

Answer 15

ok! sorry,then the simplified expression of our function is:
\[\Large \begin{gathered}
\frac{{9{x^2} + 9x - 18}}{{3x + 6}} = \frac{{9\left( {{x^2} + x - 2} \right)}}{{3\left( {x + 2} \right)}} = \hfill \\
\hfill \\
= \frac{{9\left( {x + 2} \right)\left( {x - 1} \right)}}{{3\left( {x + 2} \right)}} = 3\left( {x - 1} \right) \hfill \\
\end{gathered} \]

Answer 16

k

Answer 17

namely we have to search for the graph of the function:
y= 3x-3

Answer 18

so the slope is 3 right?

Answer 19

correct!

Answer 20

and the y intercept is -3?

Answer 21

right!

Answer 22

so its D?

Answer 23

if I set y=0, then I get x=1, so our line has to pass at point (1,0)

Answer 24

SO its D

Answer 25

furthermore if I set x=2 then I get y=3, so correct!! :)

Answer 26

kk thanks can u help me with a couple more?

Answer 27

I'm very sorry I have to go to sleep now, since it is 00:20 (Italy time zone) from me

Answer 28

Answer 29

thanks!! from Italy :)
