Answer:

x=2

Step-by-step explanation:

3(5x+2)=8x+20

First, we distribute the 3.

15x+6=8x+20

Now we can subtract 8x from both sides of the equation.

7x+6=20

Next, we subtract 6 from both sides.

7x=14

Finally, we divide both sides by 7.

x=2

Answer:

x = 2

Step-by-step explanation:

3(5x + 2) = 8x + 20

<em>open the parenthesis </em>

15x + 6 = 8x + 20

<em>subtract 8x from both sides of the equation</em>

15x - 8x + 6 = 8x - 8x + 20

7x + 6 = 20

<em>subtract 6 from both sides of the equation</em>

7x + 6 - 6 = 20 - 6

7x = 20 - 6

7x = 14

<em>divide both sides of the equation by 7</em>

7x/7 = 14/7

x = 14/7

x = 2

Given that f(–2.4) = -1 and f(-1.9) = -8, approximate<br> f'(-2.4).<br> f'(-2.4)
lora16 [44]

Answer:

f'(-2.4) ≈ -14

General Formulas and Concepts:
<u>Algebra I</u>

Coordinate Planes

  • Coordinates (x, y)

Slope Formula: \displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}

Functions

  • Function Notation

<u>Calculus</u>

Differentiation

  • Derivatives
  • Derivative Notation

Step-by-step explanation:

*Note:

The definition of a derivative is the slope of the <em>tangent</em> <em>line</em>.

<u>Step 1: Define</u>

<em>Identify.</em>

f(-2.4) = -1

f(-1.9) = -8

<u>Step 2: Differentiate</u>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.

  1. [Derivative] Set up [Slope Formula]:                                                           \displaystyle f'(-2.4) \approx \frac{f(x_2) - f(x_1)}{x_2 - x_1}
  2. Substitute in coordinates:                                                                           \displaystyle f'(-2.4) \approx \frac{-8 - -1}{-1.9 - -2.4}
  3. Evaluate:                                                                                                       \displaystyle f'(-2.4) \approx -14
