Given: f(x)= x+2 and h(x)= 1/x-1<br><br> find 2f(x)-h(x)
kow [346]

All you have to do here is replace f(x) with x + 2 and h(x) with 1/x-1.

It's like plugging in a number for x, but instead you are plugging in a whole function instead of just a number. Whenever you are pluging something in, whatever it is, make sure it is in parentheses: ( ) always!

Until your understanding of algebra becomes stronger.

2f(x)-hx

First lets plug in x + 2 for f(x). It's gonna look like this:

2(x + 2) - h(x)

Notice how I put x + 2 in parentheses next to the 2, you

a l w a y s want to do this. Now we just do the same for h(x):

2(x + 2) - (1/x - 1)

And that's it. That's all you have to do.

\dfrac{o+4m+p}{6}=e\qquad\text{multiply both sides by 6}\\\\o+4m+p=6e\qquad\text{subtract o and 4m from both sides}\\\\\boxed{p=6e-o-4m}

(1) What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of negative 5/6 (all fractio
Andreyy89
Formula for point-slope: y - y1 = m(x-x1)
Plug in the values (1): y + 4 =  -\frac{5}{6} (x - 8)  {Choice B}
Plug in the values (2): y + 6 =  \frac{1}{3}(x+ 2)  {Choice C}
_______________________

[For (3) and (4) we need to solve for slope]

(3)
First, solve for slope.
Formula for slope: \frac{y2-y1}{x2-x1}
Plug in values: \frac{-1-5}{-4-7} = - \frac{6}{11}
Slope: - \frac{6}{11}
Second, we must plug into point-slope form. 
Formula for point-slope: y - y1 = m(x-x1)
Plug in the values: y + 1 = - \frac{6}{11}(x + 4)   {Choice C}


(4)
First, solve for slope.
Formula for slope: \frac{y2-y1}{x2-x1}
Plug in values: \frac{6-(-8)}{-4-7} = - \frac{14}{11}
Slope: - \frac{14}{11}
Second, we must plug into point-slope form. 
Formula for point-slope: y - y1 = m(x-x1)
Plug in the values: y - 6 = - \frac{14}{11}(x + 4)   {Choice D}
