another math question help please!!! :)

Test Preparation SAT Preparation
1

<p>Write the point-slope form of an equation of the line that passes through the given point and has the given slope.</p>

<p>(-5, 9)</p>

<p>m = -7/8</p>

<p>Answer the question using the form y + A = B(x + C).</p>

<p>A=?
B=?
C=?</p>

<p>Express the function in the form f 0 g.
F(x) = cos(sqrt(x))</p>

<p>f(x) = cos(x)</p>

<p>g(x)= ????</p>

<p>Thanks so much</p>

<p>If anybody has AIM that i could talk to them, that would help .</p>

<p>point slope form would be:
y-y1=m(x-x1)
so, plugging in your numbers, it would be:
y-9=(-7/8)(x+5)</p>

<p>I'm guessing A=-9 B=(-7/8) C=-5</p>

<p>For the second quesiton, I can't remember what f 0 g was..</p>

<p>bump .....</p>

<p>err, is it an SAT I or II question?</p>

<p>@Redwood :
your second question
is it given that F(x) = fog (x) ?
if yes, you have :
cos (sqrtx) = f ( g(x) ) = cos (g(x)) => g(x) = sqrt x</p>
