Answer:

A(-2,2);B(6,2);C(6,-2);D(-2,-2)

Step-by-step explanation:

If the given figure is dilated by a scale factor of 4, that means the figure will be four times bigger.

We can get the coordinates of the dilated ifigure by using the scale factor on each coordinate.

The given figure has coordinates: A'(-0.5, 0.5), B'(1.5,0.5), C'(1.5, -0.5) and D'(-0.5,-0.5)

So, the dilated coordinates are

A(-2,2);B(6,2);C(6,-2);D(-2,-2)

At the end of a recent WNBA regular season, the Phoenix murmur had 12 more victories than losses. The number of victories they h
Hoochie [10]

Answer:

34 games


Step-by-step explanation:

let the number of losses be  l

let the number of victories be  v


<u>the Phoenix murmur had 12 more victories than losses:</u>

v=l+12

<u>The number of victories they had was one more than two times the number of losses:</u>

v=2l+1


<em>We have 2 expressions for v, equating these 2, we can solve for l:</em>

l+12=2l+1\\12-1=2l-l\\11=l

So 11 games, they lost.

Using this value, we can plug into the 1st equation to solve for v:

v=l+12\\v=11+12\\v=23

So 23 games, they won.


Given that no draws, they played a total of 23 + 11 = 34 games this season

What is y=2x^2-12x+16 in vertex form
Natasha2012 [34]

Answer:

y = 2(x-3)^2 - 2

Step-by-step explanation:

y = 2x^2 - 12x + 16

y = 2(x^2 - 6x + 8)

y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket


y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)

y = 2(x-3)^2 - 2
