Solve the following system of equations by substitution. PLEASE HELP!
BartSMP [9]

Answer:

(1,-1)

Step-by-step explanation:

y = -1

5x+7y = -2

Substitute the first equation into the second

5x + 7(-1) =-2

5x -7 = -2

Add 7 to each side

5x-7+7 = -2+7

5x= 5

Divide by 5

5x/5 = 5/5

x =1

(1,-1)

Help me please please
Wittaler [7]

Answer:

It is right

Step-by-step explanation:

Because the hypotenuse must be greater than all the legs, we have that 17 is the hypotenuse. So, we want to determine if 8^2+15^2=17^2.

8^2=8*8=64\\15^2=15*15=225\\17^2=17*17=289\\225+64=289\\

This means the triangle is indeed right!

How many ways can a dozen books be placed on four distinguishable shelves if no two books are the same, and the positions of the
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
