Work out the value of 16^-1/4
____ [38]

Answer:

1/2

Step-by-step explanation:

16^-1/4

We know that a^ -b = 1/a^b

1/( 16^1/4)

Rewriting 16 as 2^4

1/( 2^4^1/4)

We know that a^b^c = a^ (b*c)

1/( 2^(4*4))

1/2^1

1/2

Which graph represents the solution to the given system? y=5x+4; y=5x-3

Answer:

The lines do not intersect


Discussion:

Where do the lines intersect?

5x + 4 = 5x - 3     =>                   subtract 5x from both sides

4         =       -3      =>  NO WAY! The lines do not intersect


Thank you,

MrB
