Answer:

  False

Step-by-step explanation:

 counterexample: 3 + 7 = 10 . . . . not divisible by 4

The statement is FALSE.

__

An odd number can be represented by ...

  2n+1 . . . . where n is any integer

Then a different odd number can be represented by ...

  2m +1 . . . . where m is any integer

The sum of these numbers will be ...

  (2n +1) +(2m +1) = 2n +2m +2 = 2(n +m +1)

This will be divisible by 2 for any integers m and n, but will only be divisible by 4 if exactly one of the integers m and n is odd.

What is the discriminant of 32x-4= 4x^2 + 60
hodyreva [135]

Step One

Begin by getting one side of the question equal to zero.

32x -4 = 4x^2 + 60 Add - 32x + 4 from both sides.

0 = 4x^2 + 60 - 32x + 4 Collect like terms.

0 = 4x^2 - 32x + 64

Step Two

For this question, you could divide both sides by 4. It just makes the steps later on easier.

0 = x^2 - 8x + 16

Step Three

Calculate the discriminate.

The discriminate is b^2 - 4*a*c

a = 1; b = -8; c = 16

b^2 - 4*a*c = (-8)^2 - 4*(1)(16) = 64 - 64 = 0

There is only 1 root. It is real and it is rational.

Given: (↔AB) ║ (↔CD)
nordsb [41]
1) m = y2 - y1/x2 - x1
y = mx + b
m = 7 - 0/3 - 8
y = -7/5x + 11.2
2) y= -7/5x + 12
(the slope or m stays the same because the two equations are parallel)
