Answer:

100

Step-by-step explanation:

triangles are equal to 180 degrees so in the one triangle 180-50-50=80 so that missing angel is 80 and then to creat a straight line between the missing angle m<1 and the 80 you subtract the two 180-80=100 leaving the missing angle to be 100

X-2y=1;3x-6y=3 substitution
emmainna [20.7K]

Answer:

All solutions

Step-by-step explanation:

     When solving by substitution, we will first set one equation equal to a variable, and then plug that value into the second equation as the variable. Here is what I mean;

x - 2y = 1

3x - 6y = 3

-

x = 1 + 2y

3x - 6y = 3

-

3(1 + 2y) - 6y = 3

3 + 6y - 6y = 3

3 = 3

[] Oh no! This doesn't work well. Let's graph it and see what is happening;

-> See attached

-> I have made the lines very thick so you can see the overlap, they are the same size in reality

The answer is all solutions because the graphs are exactly the same.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

What is the maximum value of the derivative of f(x)= 3x^2+x^3
son4ous [18]

Answer:

Maximum Value: ∞

General Formulas and Concepts:

<u>Calculus</u>

Basic Power Rule:

  • f(x) = cxⁿ
  • f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x² + x³

<u>Step 2: Find Derivative</u>

  1. Basic Power Rule:                    f'(x) = 2 · 3x²⁻¹ + 3 · x³⁻¹
  2. Simplify:                                    f'(x) = 6x + 3x²

<u>Step 3: Analyze</u>

We see that our derivative is the graph of some sort of parabola. The parabola would be opening upwards.

Therefore, the maximum value of the derivative would be ∞, as the parabola's output <em>y</em> infinitely increases.
