Answer:

y = 54

General Formulas and Concepts:

<u>Pre-Algebra </u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I </u>

  • Equality Properties

<u>Geometry </u>

  • Congruency
  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u> Step 1: Define</u>

3(x + 7)° = 63°

3(x + 7)° + 63° + y° = 180°

<u>Step 2: Solve for x </u>

  1. Divide 3 on both sides:                    x + 7 = 21
  2. Subtract 7 on both sides:                 x = 14

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x</em>:                    3(14 + 7) + 63 + y = 180
  2. (Parenthesis) Add:              3(21) + 63 + y = 180
  3. Multiply:                               63 + 63 + y = 180
  4. Combine like terms:           y + 126 = 180
  5. Isolate <em>y</em>:                              y = 54

I'm super confused on parts g and h because no formula is given, just the limit values. These are the values:
Mrrafil [7]

Answer:

See below.

Step-by-step explanation:

1)

So we have the limit:

\lim_{x\to 4} (f\circ g)(x)

This is equivalent to:

\lim_{x\to 4} f(g(x))

To solve, we can use the following property:

\lim_{x \to c} f(g(x))=f(  \lim_{x \to c} g(x))

Therefore, our limit is the same as:

\lim_{x\to 4} f(g(x))\\=f(\lim_{x\to 4} g(x))

We are already given that the limit as x approaches 4 of g(x) is -2. Therefore:

=f(-2)

You simply need to evaluate this to solve the limit. I don't have enough information to solve this, so maybe you have something more.

Similarly, for the second one:

2)

We have:

\lim_{x\to 4} (g\circ f)(x)\\=\lim_{x\to 4}g(f(x))

Using the same property:

=g(\lim_{x\to 4} f(x))

And we are told that this is 16, so:

=g(16)

And we just need to evaluate this to find the limit.

I hope you find this helpful!
