Answer 2

A compound inequality is an equation with two or more inequalities joined together with either "and" or "or" (for example, and ; or ). When two inequalities are joined with and, they are often written simply as a double inequality, like: . The solution of an "and" inequality is the intersection of each individual inequality in the sentence. To find the intersection, determine where the two graphs of the sentence overlap. The solution of an "or"inequality is the union of each individual inequality in the sentence. In an "or" inequality, solve the two inequalities separately and combine the solutions together.

i think it's A

Answer 3

\(\large \color{red}{-}4 < a + 2 < 10\)

Answer 4

u have minus before 4, dont u ?

Answer 5

oops . yess i do

Answer 6

good :)

Answer 7

thanks for catching that. lol :)

Answer 8

\(\large \color{red}{-}4 < a + 2 < 10\)

subtract 2 thru out

Answer 9

wat do u get ?

Answer 10

so -4 minus 2?

Answer 11

\(\large \color{red}{-}4 < a + 2 < 10\)

subtract 2 thru out

\(\large \color{red}{-}4-2 < a + 2-2 < 10-2\)

Answer 12

yes !

Answer 13

-6<a<8

Answer 14

perfect !!
so wats the answer ?

Answer 15

b !
ohh my god thankk u :))

Answer 16

a is between -6 and 8

we write it as :-

B: a E (-6,8)

Answer 17

yup ! you're good :))
