Question

Choose the correct description of the graph of the compound inequality

x - 2 > -4 and 3x less than or greater to 15.

A number line with an open circle on -2, shading to the left, and a closed circle on 5, shading to the right.

A number line with a closed circle on -2, shading to the left, and an open circle on 5, shading to the right.

A number line with an open circle on -2, a closed circle on 5, and shading in between.

A number line with a closed circle on -2, an open circle on 5, and shading in between.

Answer 1

x - 2 > -4 (add 2 to both sides)
x > -4 + 2
x > -2

3x < = 15 ....I am assuming this is less then or equal...is that correct ?

Answer 2

i think so

Answer 3

the less than or equal two sign has this sign < and with a line under it

Answer 4

the great than or equal two is:
> with a line under it

Answer 5

3x <= 15 (divide by 3)
x <= 5

so we have : x > -2 and x <= 5

Learn this...
if there is an equal sign, the circle is closed
if there is no equal sign, the circle is open
< (less then) means shading to the left
> (greater then) means shading to the right

can you figure the answer from here ?

Answer 6

,so wich one is it

Answer 7

Yukisama..I understand what the signs mean, it is in the second inequality that it says " less then or greater " that confused me.

Answer 8

ah okay :3

Answer 9

just don't need people confused i like to help out

Answer 10

im lost

Answer 11

x > -2 ...open circle on -2, shading to the right
x <= 5 ..closed circle on 5, shading to the left

so your answer is : open circle on -2, closed circle on 5, and shading in between

Answer 12

can u help with another question

Answer 13

what you got ?

Answer 14

Solve for r: C = 2pir.

r = C over 2 pi

r = 2 c all over pi

r = C over pi

r = pi times C all over 2

Answer 15

i think its the second one not sure

Answer 16

C = 2* pi * r (solve for r) -- divide by 2 * pi
C/2*pi = r

Answer 17

so would tht be the snwer

Answer 18

no..answer is the first one

Answer 19

k thanks

Answer 20

no problem :)
