Well, first they're assuming that the m<ABC = 90

The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.

It is given that BD bisects <ABC, which means it splits the angle evenly..

Giving this equation: (x-5) = (2x-6)

Solving for x  

-5 + 6 = 2x - x

1 = x

ira has 128 stamps in his stamp album he has the same number of stamps on each of the 8 pages how many stamps are on each page
den301095 [7]
There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Number of stamps that Ira has in his stamp album = 128
Number of pages that the stamp album has = 8
Then
Number of stamps in each page of the stamp album = 128/8
                                                                                     = 16
So 16 stamps are there on each page of the stamp album. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar type of problems in future without requiring any additional help.

Which of the following is the graph of f(x) = -0.5|x+3| -2?
Tcecarenko [31]

Answer:

The last graph

Step-by-step explanation:

We transform functions in the following ways:

  • multiplying the function by a number to stretch or shrink it
  • multiplying by a negative to flip the orientation of the function
  • adding/subtracting a value to the input x to shift it horizontally
  • adding/subtracting a value to the output (or outside the function operation) to shift it vertically or horizontally.

Looking at the equation we can see f(x)=-0.5\left|x+3\right|-2

  • Vertically shrunk by 0.5
  • Negative leading coefficient to flip the graph's orientation
  • Horizontal shift of the vertex of 3 units to the left from (0,-2) to (-3,-2)
  • Vertical shift of the vertex of 2 units downward (-3,0) to (-3,-2)

The last graph has vertex (-3,-2) and satisfies the the equation.
