9√256

= 9 × √256

= 9 × 16

= 144

11.

√3 × √2

= √(3 × 2)

= √6

12.

√9 × √9

= √(9 × 9)

= √81

= 9

13.

√20 × √8

= √(20 × 8)

= √160

= √(16 × 10)

= √16 × √10

= 4 × √10

= 4√10

14.

√20 × √10

= √(20 × 10)

= √200

= √(100 × 2)

= √100 × √2

How do I start this problem? I don't need help with the graphing part.
tamaranim1 [39]

Answer:

x = 6 , y = 0   (x , y) = (6 , 0)

x = 12, y = 3   (x , y) = (12 , 3)

x = 24, y = 9   (x , y) = (24 , 9)

Step-by-step explanation:

Simply plug in a x, and find a y that would make the equation true:

When x = 6:

6 - 2y = 6

6 (-6) - 2y = 6 (-6)

-2y = 0

(-2y)/-2 = (0)/-2

y = 0

When x = 6, y = 0    (x , y) = (6 , 0)

When x = 12:

12 - 2y = 6

12 (-12) -2y = 6 (-12)

-2y = -6

(-2y)/-2 = (-6)/-2

y = 3

When x = 12, y = 3   (x , y) = (12 , 3)

When x = 24:

24 - 2y = 6

24 (-24) - 2y = 6 (-24)

-2y = -18

(-2y)/-2 = (-18)/-2

y = 9

When x = 24, y = 9   (x , y) = (24 , 9)

Which number best represents Point Q on the number line below?
Bumek [7]

Answer:

<em>D. 3.5!</em>

Step-by-step explanation:

If you slowly go up the line it will be 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, if it were to carry on it would keep being .5 then the next number. Since this is not a fraction number line the answer is not A. -9/2 nor C. -7/2.
