Which expressioin can go in the blank to make the equation true? -4.5 + 4.4 + = 0

-6.7 + 6.8

-6.7 + (-6.6)

7.2 + (-7.2)

7.2 + (-7.3)

-6.7+6.8

Step-by-step explanation:

-4.5+4.4= -0.1, -6.7+6.8=0.1, so -0.1+0.1=0

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.
