Write y=x^2-2x-3 in vertex form

-BARSIC- [3]

To solve this, use the ‘completing the square’ strategy.
Leave a space to make the first two values a perfect square.
y=(x^2-2x___)-3
Divide -2 by 2 and square that number to put in the blank. Then subtract that number from outside.
y=(x^2-2x+1)-3-1
Simplify!
y=(x-1)^2-4
It is in vertex form now ;)

If ON=8x*8, LM=7x+4, NM=x-5, and OL=3y-6, find the values of x and y for which LMNO must be a parallelogram. The diagram is not

lana66690 [7]

ON = 8x • 8
LM = 7x + 4
NM = x - 5
OL = 3y - 6

OL is congruent & parallel to NM
LM is congruent & parallel to ON

So,
$8x \times 8 = 7x + 4$
Simplify
$64x = 7x + 4$
subtract 7x from both sides
$57x = 4$
divide 57 from both sides
$x = \frac{4}{57}$
Substitute x into equations
$8x \times 8 = 7x + 4 = 4 \frac{28}{57}$

$3y - 6 = x - 5$
$3y - 6 = 4 \frac{28}{57} - 5$
$3y - 6 = - \frac{28}{57}$
NM & OL = -28/57
ON & LM = 4 + (28/57)

Answer:

Son + Daughter 60%

Son - 23,625

Daughter - 16,875

Wife % - 40%

Total - 67,500

Step-by-step explanation:

1. We do 35 + 25 to get 60

2. 27000 / 40 to get 1% = 625

Then, 625 x 35 = 23,625

3. 625 x 25 = 16,875

4. 100 - 60 ( kids ) = 40%

5. 40500 ( kids ) + 27000 = 67, 500

Use distributive property to multiply: 2 1/2 x 3 1/4

FromTheMoon [43]

2 1/2= 5/2
3 1/4= 13/4
5/2•13/4= 65/8 or 8/18
Hope this helped!
