Answer:

x = - 10

Step-by-step explanation:

−3/4(x+2)=6 Multiply both sides by -4/3

- 4/3 * - 3/4 ( x + 2) = 6 * - 4/3 Simplify

(x + 2) = - 8 "Remove" the brackets

x + 2 = - 8 Subtract 2 from both sides.

x + 2 - 2 = - 8 - 2 Simplify

x = - 10

Find the slope of the tangent line to the curve f(x)=e^(x) at (0.4,1.49)

almond37 [142]

Answer:

1.49

Step-by-step explanation:

In order to find the slope of the tangent line to a given equation, and in a given point, we need to:

1. Find the first derivative of the given function.

2. Evaluate the first derivative function in the given point.

1. Let's find the first derivative of the given function:

The original function is $f(x)=e^{x}$

But remeber that the derivative of $e^{x}$ is $e^{x}$

so, $f'(x)=e^{x}$

2. Let's evaluate the first derivative function in the given point

The given point is (0.4,1.49) so:

$f'(x)=e^{x}$

$f'(0.4)=e^{0.4}$

$f'(x)=1.49$

Notice that the calculated slope of the tangent line is equal to the y-coordinate of the given point because f'(x)=f(x). In conclusion, the slope of the tangent line is equal to 1.49.
