I believe it would be A. Reflecting over the x-axis and the y-axis. I hope this helps you please let me know

Answer:

C) Reflecting over the x-axis and then reflecting over the line y = x.

Step-by-step explanation:

A rotation 90° counterclockwise will map every point (x, y) to (-y, x).

Since the x- and y-coordinates are switched, this is not a reflection across the x-axis followed by a reflection across the y-axis.

Since the y-coordinate is negated and the x- and y-coordinates are switched, this is not a translation.

Reflecting across the x-axis will negate the y-coordinate, giving us (x, -y). Following this with a reflection across y=x will switch the coordinates giving us (-y, x). This is the correct transformation.

Step-by-step explanation:

follow a few exponent rules and you can figure this out

when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal $x^{-2}$ is 1/ $x^{2}$ soooo...

mutilply the -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o

= $8^{-2/3}$ $w^{-14/3}$ $x^{10/3}$ $y^{-6/3}$ $z^{18/3}$

= 1/ $\sqrt[3]{8*8}$ * 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

= 1/ $\sqrt[3]{64}$ * 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

= 1/4* 1/ $w^{14/3}$ * $x^{10/3}$ * 1/ $y^{2}$ * $z^{6}$

The All-Clean Laundry Company washes towels for a nearby hotel. The function f(x) gives the number of loads required whenthere a

NISA [10]

Answer:

B.It takes more than 12 loads to wash 9 bins of towels.

Step-by-step explanation:

The function f(x) gives the number of loads required when there are x bins of towels to be washed.

f(x)=Number of loads

x=Bins of towels

Therefore in the inequality f(9)>12

Number of loads=12
Bins of towel =9

If f(9)>12, it means Number of loads is more than 12.

f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.

The correct option is B
