Question

Please help me I will medal and fan!!
Choose the correct description of the graph of the compound inequality:

x − 3 < −9 or x + 5 greater than or equal to 12

A number line with a closed circle on −6, shading to the left, and an open circle on 7, shading to the right
A number line with an open circle on −6, a closed circle on 7, and shading in between
A number line with an open circle on −6, shading to the left, and a closed circle on 7, shading to the right
A number line with a closed circle on −6, an open circle on 7, and shading in between

Answer 1

x - 3 < -9 ---- add 3 to both sides
x < -9 + 3
x < - 6

x + 5 >= 12 ---- subtract 5 from both sides
x >= 12 - 5
x >= 7

Learn this :
if there is an equal sign in the problem, it will have an closed circle
if there is no equal sign, it is an open circle
< less then means shading to the left
> greater then means shading to the right

do you have any ideas what the answer is now ??

Answer 2

Its either C or A by elimination

Answer 3

the -6 does not have an equal sign, so it is an open circle.....and since x < -6, it is shaded to the left.
the 7 does have an equal sign, so it is a closed circle...and since it is greater then, it is shaded to the right.
any thoughts on the answer now ?

Answer 4

c?

Answer 5
