What are the coordinates of the vertices of the image of rectangle WXYZ after the transformation Ro, 90•(x,y)? W’(-4,-1)
algol13

<u>Answer:</u>

W (-1, 4) ---> W' (-4, -1)

X (-1, 2)  ---> X' (-2, -1)

Y (2, 2)  ---> Y' (-2, 2)

Z (2, 4)  ---> Z' (-4, 2)

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

We have with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.

We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).

So,

W (-1, 4) ---> W' (-4, -1)

X (-1, 2)  ---> X' (-2, -1)

Y (2, 2)  ---> Y' (-2, 2)

Z (2, 4)  ---> Z' (-4, 2)

PLEASE HURRY!!!!!<br><br><br> What is the turning point of the graph of f(x) = |x – 4| ?
viva [34]
f(x)=|x-4|\\&#10;f'(x)=\text{sgn} (x-4)\\&#10;\text{sgn} (x-4)=0\\&#10;x-4=0\\&#10;x=4\\\\&#10;&#10;

For x f'(x).
For x>4 f'(x)>0.
\Downarrow\\&#10;
At x=4 there's turning point, which is equal |4-4|=|0|=0.

Kenny had a total of 140 minutes to read, do homework, and play video games. he spent x minutes reading. he spent 2(x + 5) minut
Mekhanik [1.2K]

Answer:

35 min

Step-by-step explanation:

given that the total time spent is 140min

and that the time spent reading is x minutes

and also that the time spent doing home work is 2(x+5)

the time spent playing video game is 25

the expression for the total time is given as

total = reading +homework +video game

140=x+2(x+5)+25

solving for x we have

140=x+2x+10+25

140=3x+35

140-35=3x

105=3x

x=105/3

x=35

kenny spent 35 min reading
