At the indicated point find (a) the slope of the curve and (b) an equation of the tangent line.

Marianna [84]

Answer:

Slope of the Curve: $f'(x)=\frac{-6}{x^2}$

Equation of Tangent Line: y + 3 = -3/2(x + 2)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Calculus

The definition of a derivative is the slope of the tangent line.

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Quotient Rule: $\frac{d}{dx} [\frac{f(x)}{g(x)} ]=\frac{g(x)f'(x)-g'(x)f(x)}{g^2(x)}$

Step-by-step explanation:

Step 1: Define

$f(x)=\frac{6}{x}$

Step 2: Take Derivative

Quotient Rule: $f'(x)=\frac{0(x)-6(1)}{x^2}$
Multiply: $f'(x)=\frac{0-6}{x^2}$
Subtract: $f'(x)=\frac{-6}{x^2}$

Step 3: Find Instantaneous Derivative

Substitute in x: $f'(x)=\frac{-6}{(-2)^2}$
Exponents: $f'(x)=\frac{-6}{4}$
Simplify: $f'(x)=\frac{-3}{2}$

This value shows the slope of the tangent line at the exact value of x = 2.

Substitute: y + 3 = -3/2(x + 2)

Solve the inequality what is the solution?

bija089 [108]

Answer:

The solution to the inequality is:

$2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}$

Please also check the graph of the solution to the inequality.

Step-by-step explanation:

Given the inequality

$2\ge \frac{g}{-4}$

switch sides

$\frac{g}{-4}\le \:2$

Multiply both sides by -1 (reverse the inequality)

$\frac{g\left(-1\right)}{-4}\ge \:2\left(-1\right)$

Simplify

$\frac{g}{4}\ge \:-2$

Multiply both sides by 4

$\frac{4g}{4}\ge \:4\left(-2\right)$

Simplify

$g\ge \:-8$

Therefore, the solution to the inequality is:

$2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}$

Please also check the graph of the solution to the inequality.
