OpenStudy (brodybarnes35):

ughhh

OpenStudy (anonymous):

thats so weird

OpenStudy (anonymous):

could you just help with other ones? i have a good amount today :/ so annoying

OpenStudy (anonymous):

yeah sure

OpenStudy (brodybarnes35):

ok one sec

OpenStudy (brodybarnes35):

The graphs of f(x) and g(x) are shown below: graph of function f of x equals x squared minus x minus 12. Graph of function g of x equals 3.4 times x minus 6.6 What are the solutions to the equation f(x) = g(x)? x = −1, 5.4 x = −3, 4 x = −1, 2 x = −10, 12

@Sammylemon

OpenStudy (anonymous):

okay... umm

OpenStudy (anonymous):

let me write it out first

OpenStudy (brodybarnes35):

OpenStudy (anonymous):

or does it look different

OpenStudy (brodybarnes35):

yaya ur right

OpenStudy (anonymous):

OpenStudy (anonymous):

okay, so now we want to set them equal to each other

OpenStudy (brodybarnes35):

okay

OpenStudy (anonymous):

Like this

OpenStudy (brodybarnes35):

okay what next

OpenStudy (anonymous):

we want to make it a quadratic equation

OpenStudy (anonymous):

to bring g(x) to the other side

OpenStudy (brodybarnes35):

ok

OpenStudy (brodybarnes35):

@Sammylemon u there?

OpenStudy (anonymous):

yeah.. did you get it

OpenStudy (anonymous):

This is what I got

OpenStudy (brodybarnes35):

so A?

OpenStudy (anonymous):

well we have to put it into the equation now

OpenStudy (brodybarnes35):

oh my b lol ok lets do it

OpenStudy (anonymous):

Plug those in

OpenStudy (brodybarnes35):

the picture wont open...

OpenStudy (brodybarnes35):

OpenStudy (anonymous):

Here

OpenStudy (brodybarnes35):

it still wont work can u just type what u were trying to show me or what u got idk???

OpenStudy (anonymous):

\[\frac{ -b \pm \sqrt{b ^{2}-4ac} }{2a }\]

OpenStudy (brodybarnes35):

Ok? idk how to do that

OpenStudy (anonymous):

a=1 b=-4.4 c=5.4

OpenStudy (anonymous):

plug those in

OpenStudy (brodybarnes35):

oh ok yikes

OpenStudy (brodybarnes35):

4.4 plus minus sqr rt -4.4^2 - 4(1* 5.4) --------------------------------- 2(1)

OpenStudy (brodybarnes35):

@Sammylemon

OpenStudy (anonymous):

Okay... I'm so sorry... But I have to go... If you aren't able to get it... Than I guess I would Go with letter a

OpenStudy (brodybarnes35):
