sorry
OpenStudy (anonymous):
Slope just tells you how much your output changes as your input changes.
OpenStudy (anonymous):
So if you have a slope of 2/3. That means each time your input changes by 3, your output changes by 2.
OpenStudy (anonymous):
oh ok
OpenStudy (anonymous):
can you help me with a problem ?

sure

\[4x ^{2}-3x+12-2x ^{2}+7x+16=\]
OpenStudy (anonymous):
This isn't really slope related. You just need to combine your 'like' terms.
OpenStudy (anonymous):
You have four \(x^2\)'s and you're taking away two \(x^2\)'s. How many \(x^2\)'s will be left?
OpenStudy (anonymous):
You have 7x's and you're taking away 3x's

2x^(2)? and 4x^{2}?
OpenStudy (anonymous):
2\(x^2\) and 4x, and 16 and 12
OpenStudy (anonymous):
what's 16 and 12?
OpenStudy (anonymous):
28
OpenStudy (anonymous):
Ok so what's your answer?

haha wait so my answer is \[2x ^{2}+4x+28\] ?
OpenStudy (anonymous):
yep
OpenStudy (anonymous):
ohh! wow so how do i show the work lol.. but thankss !
OpenStudy (anonymous):
Just move the things around.
\[4x ^{2}-3x+12-2x ^{2}+7x+16\]
\[= 4x^2 - 2x^2 + 7x -3x +12 + 16\]
\[= 2x^2 + 4x + 28\]

thankss so much
