Answer:

They are all true

Step-by-step explanation:

1. 3² +4² = 5²

3x3 + 4x4 = 5x5

  9   +  16  =  25

25 = 25

-----------------------

2. 6² + 8² = 10²

36 + 64 = 100

100 = 100

------------------

3. 9² + 12² = 15²

81 + 144 = 225

225 = 225

4. 5² +12² =13²

25 + 144 = 169

169 =169

On the graph below are three points X, Y, and Z. Write the coordinates for the given dilation. DO, -½ of Y =
DiKsa [7]

Answer:

(-\frac{3}{2},-1)

Step-by-step explanation:

From the graph in the attachment Y has coordinates:Y(3,2)

The transformation rule for a dilation with a scale factor k about the origin is:

(x,y)\to (kx,ky)

In this case we have k=-\frac{1}{2}

We substitute the coordinates and k=-\frac{1}{2} to get:

Y(3,2)\to Y'(-\frac{1}{2}*3,-\frac{1}{2}*2)

This simplifies to:

Y(3,2)\to Y'(-\frac{3}{2},-1)

The first choice is correct.

GaryK [48]

Answer:

r=0

Step-by-step explanation:

7r+6+3=9

Add 6 + 3 = 9:

7r+9=9

Subtract 9 from both sides:

7r+9-9=9-9

7r=0

Divide both sides by 7:

\frac{7r}{7}=\frac{0}{7}

r=0
