Answer:

\textsf {C. -2}

Step-by-step explanation:

\textsf{In the equation y = mx + b, m is the slope and} \\\textsf{b is the value of the y-intercept.}

\textsf {The line has a y-intercept at (0, -2), hence b = -2.}

Part 1.] Identify the transformations that describe the graph of an odd function. Select all that apply.
Zarrin [17]
Hello,

1) A odd function has the propriety f(-x)=-f(x)
Answer E

2)
if f(x) is even f(x)=f(-x)
if g(x) is even g(x)=g(-x)

h(x)=f(x)+g(x)=(f+g)(x)
h(-x)=(f+g)(-x)=f(-x)+g(-x)=f(x)+g(x)=(f+g)(x)=h(x)

h(x) is even

Who can help me ! <br> .... thanks
Tasya [4]
Given that there is no any option to choose I am going to help you according to the concepts of Congruent Triangles. Two triangles are congruent if and only if:

1. They have:exactly the same three sides
2. exactly the same three angles.

<span>There are five ways to find if two triangles are congruent but in this problem we will use only two.


First Answer:

<u>ASA criterion:</u> </span><em>A</em><span><em>ngle, side, angle</em>. This means that we have two triangles where we know two angles and the included side are equal.</span>

So:

If ∠BAC = ∠DEF and \overline{AC}=\overline{DE}

<em>Then ΔABC and ΔEFD are congruent by ASA criterion.</em>

Second answer:

<u>SAS criterion:</u> <em>S</em><span><em>ide, angle, side</em>. This means that we have two triangles where we know two sides and the included angle are equal.
</span>
If \ \overline{AC}=\overline{DE} \ and \ \overline{BC}=\overline{DF}

<em>Then ΔABC and ΔEFD are congruent by SAS criterion.</em>

In need of geometry help, once again my stupid brain cant remember anything.
melomori [17]

You cannot rely on the drawing alone to prove or disprove congruences. Instead, pull out the info about the sides and angles being congruent so we can make our decision.

The diagram shows that:

  • Side AB = Side XY (sides with one tick mark)
  • Side BC = Side YZ (sides with double tickmarks)
  • Angle C = Angle Z (similar angle markers)

We have two pairs of congruent sides, and we also have a pair of congruent angles. We can't use SAS because the angles are not between the congruent sides. Instead we have SSA which is not a valid congruence theorem (recall that ambiguity is possible for SSA). The triangles may be congruent, or they may not be, we would need more information.

---------------

So to answer the question if they are congruent, I would say "not enough info". If you must go with a yes/no answer, then I would say "no, they are not congruent" simply because we cannot say they are congruent. Again we would need more information.
