The sum of a number, x, and 1/2 is equal to 4. Which set of equations correctly represents x? A. 4=x + 1/2
x= 4 1/2
B. 4=1/2x
x=2
C. 4=1/2x
x=8
D. 4= x+1/2
x= 3 1/2

what?

step-by-step explanation:

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.

step-by-step explanation:

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
