(f(8)-f(4))/(8-4)

(4-12)/4

-8/4

-2

the average rate of change is -2.
Hope this helps.

Irspow i know are answers are similar but its the only way i could give all the useful information needed for this question so AlwaysFancyNancy could understand the problem for the question hope you understand.

The average rate of change is the change in y divided by the change in x...

(f(8)-f(4))/(8-4)

(4-12)/4

-8/4

-2

So the average rate of change is -2.

Answer:

3) Reflexive Property

4) SAS

Step-by-step explanation:

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

Example: a = a
In this case, it could be seen as ST ≅ ST because they have/are the same side(s).

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

Example: RST ≅ UTS (both have S and T)
Can be seen as RST ≅ UST as well to make their similarity more evident.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

What is the reflection image of P(0, 0) after two reflections, first across x = 4 and then across y = -3?

jek_recluse [69]

Answer:

The reflection image of P(0, 0) after two reflections is (8,-6)

Step-by-step explanation:

step 1

Find the coordinates of point P after reflection across x=4

we know that

The distance from point P to the line x=4 is equal to 4 units

(0,0) -----> (4+4,0) ----> (8,0)
