Answer:

y = 3

Step-by-step explanation:

y - 3 = 2(x + 1)

If you simplify the right side of the equal sign, you'll get...

y - 3 = 2x + 2

then you would add 3 to both sides...

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

which will make...

y = 2x + 5

and since x = -1, you plug it in..

y = 2(-1) + 5

which will give you..

y = -2 + 5

which will make it..

y = 3

Jet001 [13]

Answer:

217945728000 ways

Step-by-step explanation:

Given

Books = 12 --- 1 dozen

Shelf = 4

The given condition implies that;

Book\ 1  = 4 ---- any of the 4 shelves

Book\ 2  = 5 --- any of the 4 shelves and either ways of book 1

Book\ 3  = 6  --- any of the 4 shelves and either ways of book 1 and 2

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

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

----------

<h2>Book\ 12 = 15</h2><h2></h2>

So, the number of ways is:

Ways = 4 * 5 * 6 * 7 * 8 * 9 * 10 * 11 * 12 * 13 * 14 * 15

Ways = 217945728000

Please help, seriously confused
Rufina [12.5K]
Original height = original width = x mm

1. She made an enlarged copy...
height = 2x
width = 2x

2. She cut off a rectangle...
height = 2x
width = \frac{2}{3} *2x= \frac{4}{3}x

3.She doubled the width...
height = 2x
width = 2*\frac{4}{3}x = \frac{8}{3}x

height * width = area

2x * \frac{8}{3}x=139 \ 968  \\ \\ \frac{16}{3}x^2= 139 \ 968 \\\\ x^2=139 \ 968: \frac{16}{3}=139 \ 968 * \frac{3}{16}=  8 \ 748*3 = 26 \ 244 \\  \\ x= \sqrt{26 \ 244} = 162 \ mm

Original height was 162 mm
