What is the difference of 8 and 9 written as an addition problem?
a. 8 + (−9)
b. 8 − (−9)
c. 9 + 8
d. 9 + (−8)

step-by-step explanation:

since you are looking for a difference 9 has to be subtraced from since you want it in the form of an addition problem, 8 + (-9) would fit the bill,   a           (though poorly worded problems are somewhat may say that d would also work)

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.
