Answer:

22

Step-by-step explanation:

Since the 2 triangles shown are congruent, the corresponding angles are equal.

Angle A corresponds to angle D. <em>We set them equal and solve for x:</em>

<em>2x+8=52\\2x=52-8\\2x=44\\x=\frac{44}{2}\\x=22</em>

<em />

First answer choice, 22 is right.

Given the graph below, which of the following statements is true?
Elza [17]

Answer:

Option d is right

Step-by-step explanation:

A function is called one to one if two x will not have same y value.

In other words, in the domain each x is matched with a unique y and if x1 not equals x2 we have the corresponding y1 will not be equal to y2.

In the graph given, we find that the y value say 1 has preimages in both to the right of y axis and to the left of y axis.

Hence this is not one to one.

This is a function because each x has a unique image. If we draw a vertical line in any part of the graph we find that it  cuts only one time the graph of f(x)

Hence f is a function but not one to one.  A one to one function need not pass through the origin.

Hence we find that of the options given, a,b and c are wrong.

But option d is right.
