<h3>Answer:</h3>

The transformation is a rotation.

<h3>Step-by-step explanation:</h3>

The incorrect answers can be ruled out as follows:

dilation would change the size, but not the directions of the lines
reflection would change the DEF ordering from clockwise to counterclockwise
translation would move the figure, but not change the directions of the lines

The image is the same size as the original. Each of the sides of the triangle is moved through the same angle. The transformation is a rotataion.

The center of rotation can be found as the point of intersection of the perpendicular bisectors of DD', EE' and FF'

Answer:

$\displaystyle -2$

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

Brackets

Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

<u>Algebra I</u>

Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

<u>Step 1: Define</u>

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

<u>Step 2: Find Average</u>

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$

Need help ASAP it’s due at 12! The screen couldn’t fit, this is the clearest pic I can get! If anyone can help it will be greatl

Tamiku [17]

Step-by-step explanation:

Since ,

Money lended =$400

Intetest =27.74%

Therefore,

Intetrst=p×r×t/100,if interested monthly

=400×27.74×1/100(interested monthly)

=4×27.74

=$110.96

Interest=p×r×t/100×1/12,if interested anually

=400×27.74×1/100/12

=110.96/12

=$9.24 or it will be $110.96 if it is interested anuaaly..
