Step-by-step explanation:

First, replace f(x) with y ⇒ f(x)=6x-19 ⇒ y=6x-19

Then y with x and x with y ⇒ y=6x-19 ⇒ x=6y-19

Solve the equation from for y:

x=6y-19

x+19=6y dividing with 6

1/6 x +(19/6) = y

Replace y with f−1(x) ⇒ f−1(x)= 1/6 x +(19/6)

hope this helps!

Triangle ABC is reflected across the x-axis, and then across the y-axis. Which rotation is equivalent to this composition of tra

larisa [96]

Answer:

C) 180 degree rotation

Step-by-step explanation:

While reflecting a point, with coordinates as (x, y), over x axis the new co-ordinates become (x, -y)

⇒(x, y) → (x, -y)

While reflecting a point, with coordinates as (x, y), over y axis the new co-ordinates become (-x, y)

⇒(x, y) → (-x, y)

So, when these two operations are combined, they the rule followed is,

⇒(x, y) → (-x, -y)

We also know that while rotating a point, with coordinates as (x, y), 180° the new co-ordinates become (-x, -y)

⇒(x, y) → (-x, -y)

Therefore, reflecting a point over x axis and then over y axis will yield the same result as rotating a point 180°.

Answer:

3, -8 , 11.

Step-by-step explanation:

f(x) = (x - 3)(x + 8)(x - 11)

Finding the zeros:

(x - 3)(x + 8)(x - 11) = 0

x - 3 = 0 gives x = 3.

x + 8 = 0 gives x = -8.

x - 11 = 0 gives x = 11.

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (4, -8)

Point (7, -10)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(7-4)^2+(-10+8)^2}$
(Parenthesis) Subtract/Add: $\displaystyle d = \sqrt{(3)^2+(-2)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{9+4}$
[√Radical] Add: $\displaystyle d = \sqrt{13}$
