-2r + 3 greater then or equal to 19

Third One ( 8 with filled dot going left )

Step-by-step explanation:

Once the inequality is solved

r ≤ -8

its going negative since it's a less than or equal to sign.

When an inequality has a

LESS THAN OR EQUAL TOO

GREATER THAN OR EQUAL TOO

sign the dot is closed

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
