Find the indicated derivative.
Dahasolnce [82]
Oof, division rule:
(f/g)'=(f'g-fg')/g^2
Let (9t-8)^6=f and t+2=g
Thus we get
(9*6(9t-8)^5*(x+2)-(9t-8)^6)/(x+2)^2
(54(9t-8)^5*(x+2)-(9t-8)^6)/(x^2+4x+4)

I'm not sure how much I'm supposed to simplify this...

From the set {1, 3, 4}, use substitution to determine which value of x makes the equation true.
Harlamova29_29 [7]

30 - 2x= 22

-2x = 22 - 30

-2x = -8

(dived both sides by -2)

x= 4

What is the slope of the line that passes through the points (8,-8) and (5,-1)?
dezoksy [38]

Hey there!

  • Answer :

\sf{ \purple{ \boxed{\bold{m =  -  \dfrac{7}{3} }}}}

\\

  • Explanation :

We are given the points \sf{P_1(\overbrace{ \blue{8}}^{\blue{x_1}} ,\underbrace{\orange{-8}}_{ \orange{y_1}}) \: and \: P_2(\overbrace{ \green{5}}^{\green{x_2}} ,\underbrace{\red{-1}}_{\red{y_2} })} . To find the slope \sf{\purple{m}} of such a line, we use the slope formula which is the following:

\sf{ \purple{m} }=  \dfrac{\Delta y}{\Delta x}  =  \dfrac{ \red{y_2} - \orange{y_1}}{ \green{x_2 }- \blue{x_1}}

\\

⇢Now, by plugging in our values, we get :

\sf{ \purple{m}} =  \dfrac{ \red{ - 1} -  \orange{( - 8)}}{ \green{5} \:   -  \:  \blue{8}}  =  \dfrac{ \:  \: 7 \: }{ -  3 \: }  \\  \\  \implies \sf{ \purple{ \boxed{m =  -  \dfrac{7}{3} }}}

Therefore, the slope of the line is \sf{ \purple{ \boxed{m =  -  \dfrac{7}{3} }}}
