Which point would not be a solution to the system of linear inequalities shown below?
Anna11 [10]

Answer:

The coordinates (12,7) would NOT be a solution to the system of linear inequalities shown below.

Step-by-step explanation:

If you do the graphing and you look at all your options of coordinates, (12,7) is the only one that is not in the shaded areas or in the lines of the inequalities. Therefore, (12,7) should be the answer to that question. :)

Hey guys how do you simplify this fully?​
Masja [62]

Answer:

32

Step-by-step explanation:

In 100^1000,

100 can be written as,

100 = 10 x 10 = 10^2

100^1000

= 10^( 2 * 1000 )

= 10^2000

10 can be written as,

10 = 2 x 5

10^2000

= ( 2 x 5 )^2000

Formula : -

( a x b )^n = a^n x b^n

Here,

a = 2

b = 5

n = 2000

( 2 x 5 )^2000 = 2^2000 x 5^2000

[ 2^2005 x 5^2000 ] / 100^1000

= [ 2^2005 x 5^2000 ] / [ 2^2000 x 5^2000 ]

Formula : -

a^m x b^n / a^c x b^d

= a^( m - c ) x b^( n - d )

Here,

a = 2

m = 2005

c = 2000

b = 5

n = d = 2000

[ 2^2005 x 5^2000 ] / [ 2^2000 x 5^2000 ]

= 2^( 2005 - 2000 ) x 5^( 2000 - 2000 )

= 2^5 x 5^0

{ Note : Any number power 0 ( except 0 ) is 1.

That is 0^0 ≠ 1, but 5^0 = 1. }

= 2^5 x 1

= 2^5

= 2 x 2 x 2 x 2 x 2

= 32

Write an equation of the line that passes through ( -4. – 1) and is perpendicular to the line y= 4/3x+6.
Gnom [1K]

Answer:

y = -3/4x -4

Step-by-step explanation:

y = -3/4x + b

-1 = -3/4(-4) + b

-1 = 12/4 + b

-1 = 3 + b

-4 = b

y = -3/4x -4
