Find the point on the graph of the given function at which the slope of the tangent line is the given slope.
mezya [45]

Answer:

A ( -2 , 9 )

Step-by-step explanation:

<u>Idea:</u> You find the first derivative of f(x), and then set it equal to the desired slope. You'll find some x. That we will use to find the point.

f'(x) = 3x^2 + 12x + 20

f'(x) = 8

3x^2 + 12x + 20 = 8

3x^2 + 12x + 12 = 0

3 ( x^2 + 4x + 4 ) = 0

3 ( x + 2 )^2 = 0

x + 2 = 0

x = -2

So, the desired point is:

A ( -2, f(-2) ) --> A ( -2 , 9 )

-5x-18y=-28 and -10x+9y=-11 solve elimination
Dmitry [639]

Answer:

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=2,\:y=1

Step-by-step explanation:

Given the equations

-5x-18y=-28

-10x+9y=-11

solving the system of the equation by elimination method

\begin{bmatrix}-5x-18y=-28\\ -10x+9y=-11\end{bmatrix}

\mathrm{Multiply\:}-5x-18y=-28\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-10x-36y=-56

\begin{bmatrix}-10x-36y=-56\\ -10x+9y=-11\end{bmatrix}

-10x+9y=-11

-

\underline{-10x-36y=-56}

45y=45

\begin{bmatrix}-10x-36y=-56\\ 45y=45\end{bmatrix}

solve 45y=5 for y:

45y=45

\frac{45y}{45}=\frac{45}{45}

y=1

\mathrm{For\:}-10x-36y=-56\mathrm{\:plug\:in\:}y=1

solve -10x-36\cdot \:1=-56 for x:

-10x-36\cdot \:1=-56

-10x-36=-56

Add 36 to both sides

-10x-36+36=-56+36

-10x=-20

\frac{-10x}{-10}=\frac{-20}{-10}

x=2

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}
