Answer:

∠ L = 109°

Step-by-step explanation:

Since the triangles are congruent, then corresponding angles are congruent.

Thus ∠ J = ∠ G , substitute values

3x + 12 = 2x + 19 ( subtract 2x from both sides )

x + 12 = 19 ( subtract 12 from both sides )

x = 7

Then

∠ G = 2x + 19 = 2(7) + 19 = 14 + 19 = 33°

∠ H = 4x + 10 = 4(7) + 10 = 28 + 10 = 38°

By the sum of angles in a triangle = 180°, then

∠ F = 180° - (33 + 38)° = 180° - 71° = 109°

∠ F and ∠ L correspond , thus

∠ L = ∠ F = 109°

Justin has written 5 novels with an average length of 450 pages. If his sixth novel is 750 pages long, what is the average lengt
OLga [1]

Answer:

  • <u><em>Option A: 500 pages</em></u>

Explanation:

<u>1. Number of pages of the first 5 novels</u>

  • Average = [Number of pages] / [number of novels]

  • 450 pages / novel = Number of pages / 5 novels

  • Number of pages = 5 novels × 450 pages / novel = 2,250 pages

<u>2. Average length of all 6 novels</u>

  • Average = [Number of pages] / [number of novels]

  • Number of pages of 6 novels = 2,250 pages + 750 pages = 3,000 pages

  • Average = 3,000 pages / 6 novels = 500 pages / novel

Given the table of values below, which of the following ordered pairs are found on the graph of the inverse function? A. (-2, -1
Ainat [17]

Given:

The of values of a function.

To find:

The ordered pairs that are found on the graph of the inverse function.

Solution:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

Then its inverse function is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

From the given table it is clear that, the ordered pairs of the function f(x) are :

\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}

So, ordered pairs of the inverse function are :

\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}

Therefore, the correct option is B.
