The difference of the answers between (-2)^4 and -2^4

Step-by-step explanation:

hello :

(-2)^4 = (-2)× (-2)× (-2)× (-2) =+16

but : -2^4 = - ((2)× (2)× (2)× (2)) = -(+16) = -16

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
