Find the equation of the tangent line to g(x) = 4x² + 6x at x = 0 Simplify any fractions

Marina CMI [18]

Answer:

y = 6x

To find equation,

1) Find Derivative

2) Find the slope at x

3) Find coordinates

<h3>Lets first Derive The Equation</h3>

$\sf \rightarrow y = 4x^2 + 6x$

$\sf \rightarrow \dfrac{dy}{dx} = (2)4x^{2-1} + (1)6x^{1-1}$

$\sf \rightarrow \dfrac{dy}{dx} = 8x + 6$

Secondly find Slope at x = 0

$\sf \rightarrow \dfrac{dy}{dx} = 8(0) + 6$

$\sf \rightarrow \dfrac{dy}{dx} = 6$ Yep so the slope(m) is 6.

Recall, tangent line has the same slope.

Now third step is to find coordinates

At x = 0, y = 4x² + 6x ⇒ y = 4(0)² + 6(0) = 0 $\star$ so coordinates: (0, 0)

Equation:

y - y₁ = m(x - x₁)

y - 0 = 6(x -0)

y = 6x

The value of x in this system of equations is 1. 3x + y = 9 y=-4x + 10

exis [7]

Answer:

x=1

Step-by-step explanation:

First we have to isolate y

Subtract 3x from both sides:

y=-3x+9

y=-4x+10

Multiply the bottom by -1:

y=-3x+9

-y=4x-10

Combine the equations:

x-1=0

Add 1 to both sides:

x=1
