To find the value of the variable of an inequality, you must isolate it, or get it by itself, on one side of the inequality sign. To do that, use inverse operations on both sides of the inequality sign. That means undoing or "canceling out" the effects of an operation by using its opposite operation. If you see addition, use subtraction, and vice versa. If you see multiplication, use division, and vice versa. Use the same operation and numbers on both sides. How can you isolate the variable in this inequality? 3b < -99. A Subtract 99 from 3b. B Add 99 to both sides. C Divide both sides by 3. D Multiply both sides by 3.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.

the 3rd on is correct

step-by-step explanation:

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
