What will be the result of substituting 2 for  x  in both expressions below?  

1/2x + 4

x + -1/2x - 2

both expressions equal 5 when substituting 2 for  x  because the expressions are equivalent.

both expressions equal 6 when substituting 2 for  x  because the expressions are equivalent.

one expression equals 5 when substituting 2 for  x,  and the other equals 2 because the expressions are not equivalent.

one expression equals 6 when substituting 2 for  x,  and the other equals 2 because the expressions are not equivalent.

Step By Step:

With each expression we will first simplify (combine like terms), then substitute, and then solve.

First Expression:

1/2x + 4

Simplify:

There is no like terms so we result in 1/2x + 4 still

Substitute:

1/2x + 4

1/2(2) + 4

Solve:

1/2(2) + 4

1 + 4 = 5

Second Expression:

x + -1/2x - 2

Simplify:

x + -1/2x - 2

1/2x + (-2)

Substitute:

1/2x + (-2)

1/2(2) + (-2)

Solve:

1/2(2) + (-2)

1 + (-2)

1 - 2 = -1

None of the answers are correct from what I can see. Although, we do know that the two expressions are not equivalent considering we got two completely different answers, so your answer could not be A or B. Next, we know that one expression equals 5, which can remove D and leave us with only C. This leaves us with only to guess of what the answer is.

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.
