All of the following expressions are equal except 4^2/4^5 4-^3 1/4^3 4^5/4^2

D.

Step-by-step explanation:

We are asked to find the expression, which is not equivalent from our given choices.

A.

Using exponent property , we will get:

Using exponent property , we will get:

Therefore, option A, B and C are equivalent.

Let us check option D.

D.

Using exponent property , we will get:

Therefore, option D is the correct choice.

answear:

a

step-by-step explanation: a

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
