Answer: A and D

<u>Step-by-step explanation:</u>

You are correct with the first answer: reflection across the x-axis

You are WRONG with the second answer: It is inside the absolute value so it is horizontal (not vertical). It is a stretch by a factor of $\frac{1}{3}$ , which I am assuming is the same as a compression by a factor of 3. The correct answer is: horizontal compression by a factor of 3.

Find the perimeter of △ABC with vertices A(−5, 3), B(4, −5), and C(−5, −5). Round your answer to the nearest hundredth.

The perimeter of △ABC with vertices A(−5, 3), B(4, −5), and C(−5, −5) is 29.04 units

<h3>Perimeter of a triangle</h3>

The perimeter of a triangle is the sum of the sides of the triangle.

Given the coordinate points A(−5, 3), B(4, −5), and C(−5, −5)

Determine the distance AB, AC and BC using the distance formula

AB = √(-5-3)²+(4+5)²

AB = √64+81
AB = √145

AB = 12.04 units

AC = √(-5-3)²+(-5+5)²

AC = √64

AC = 8 units

BC = √(-5-4)²+(-5+5)²

BC = √81
BC = 9 units

Take the sum

Perimeter of triangle ABC = 9 + 8 + 12.04

Perimeter of triangle ABC = 29.04 units

Hence the perimeter of △ABC with vertices A(−5, 3), B(4, −5), and C(−5, −5) is 29.04 units

The yearbook club had a meeting. The meeting had 6 people, which is two-thirds of the club. How many people are in the club?

timofeeve [1]

The answer would be 9 because if you add one more 3rd to the number 6 that would be 3 so 3 * 3 = 9 there are 9 people in the book club

The triangle are congruent.
The one is 5 times longer on the base therefore the height is 5 times higher,
