Which graph shows the solution to the inequality <br> |x+3| ≥ 2?
KIM [24]

Answer:

2nd number line

Step-by-step explanation:

When there is an absolute value inequality of the form  |x+a| ≥ b,

We can say that the solution set (in a number line) would be:

  • we take the point x = -a
  • then we go b units in both directions (left and right)
  • start from those 2 points and draw arrows in both directions (left & right)

Keeping these points in mind,

|x+3| ≥ 2

we start from x = -3

we go 2 units left and right, so we arrive at x = -5 and x = -1

then we draw arrows to both sides

<em>looking at the choices, </em><em>we see 2nd answer choices (graph) portrays it correctly.</em>

10*2 = 20 feet.

3. Divide the 9cm by 3cm, then multiply by 8 km

9/3 = 3

3*8 = 24 kilometers.

4. Divide real distance by distance on map:

36 / 4 = 9

1 inch = 9 miles

5. Divide real dimension by the drawing dimension:

21 meters / 3 centimeters = 7

1 cm = 7 meters
