Anything multiplied by 0 is 0, so the answer is 0. Even infinity has that law

lol why diu

(y2 - y1)/(x2 - x1)

The answer to the question is 50

Its just 50. You know how to count by 10's?

2. x^2 + 6x   = -5    add 5 to both sides

   x^2 + 6x + 5   = 0        factor

(x + 5) ( x + 1)   = 0       set each factor to 0

x + 5  = 0                   x + 1   = 0

x = -5                          x = -1               and these are the solutions

3.  x^2 + 14x + 112  = 0      

Using the discriminant  we have

14^2  - 4(1)(112)  =

196 - 448  =

-252   ....so    this has no real solution

Solve for x 
x^2 + 6 x = -5

Add 9 to both sides:
x^2 + 6 x + 9 = 4

Write the left hand side as a square:
(x + 3)^2 = 4

Take the square root of both sides:
x + 3 = 2 or x + 3 = -2

Subtract 3 from both sides:
x = -1 or x + 3 = -2

Subtract 3 from both sides:
Answer: | x = -1        or          x = -5

Solve for x:
x^2 + 14 x + 112 = 0

Subtract 112 from both sides:
x^2 + 14 x = -112

Add 49 to both sides:
x^2 + 14 x + 49 = -63

Write the left hand side as a square:
(x + 7)^2 = -63

Take the square root of both sides:
x + 7 = 3 i sqrt(7) or x + 7 = -3 i sqrt(7)

Subtract 7 from both sides:
x = 3 i sqrt(7) - 7 or x + 7 = -3 i sqrt(7)

Subtract 7 from both sides:
Answer: | x = 3 i sqrt(7) - 7         or            x = -3 i sqrt(7) - 7

P.S. Neither solution agrees with your multiple choices!!.

Take the derivative and set this to 0......and we have

3x^2 - 3   = 0

3(x^2 - 1) = 0    divide by 3

x^2 - 1   = 0        factor

(x + 1) (  x - 1)  = 0    setting each factor to 0 and we have that

x = - 1     and  x = 1    so  these are the critical points

Taking the second derivative, we have

6x   .......   and putting x = 1   into this  we get   6(1)  = 6

This indicates a minimum when x = 1   and y = (1)^3 - 3(1)   =  -2

So....the minimum point is -2 when x > 0

wat is da 97th power to 190,674

190,674^(1/97) =1.1335377674334057464609644574147........etc.

Do you mean  (445^2)^3  ?

Using Web2.0 calculator:

(7/4)(7^2)*(tan(180/7))^-1 = 178.0617097559035774         Note : I had to put the multiplication sign between the parens before tan to get it to work     AND this is in DEGREES

     Wow, I forgot you can combin like terms and distrubutive prop.

OHHHHHHHHHHH 

-3 (x+2) = -3(x) -3(2) = -3x -6     distributive property of multiplcation

Can you go into detail on how you got the 6 from (x+2)

Original cost   x  (1- .27) = off season price

Use distributive propert first to get:

-3x - 6 = 7      Add 6 to both sides

-3x = 13       divide both sides by -3

x = - 13/3 = - 4 1/3

I don't think infinity is a number...it is more like a concept of a never ending parade of numbers....or space.

It can be used as a symbol to describe a never ending trend. If we are talking numbers, i could just give you a computer that just keeps generating numbers and never stops. The numbers are there but we describe it as infinite.

Infinity is a # it just keeps going on and on so it is a increasing number
