It is stated that their are closed circles on -4 and 3. This means, both -4 and 3 are also included in the interval.

The following regions are included in the range:

a) -4 
b) Numbers between -4 and 3
c) 3
d) Numbers greater than 3

So, the number line represents:
x greater than or equal to -4 and x less than or greater to 3.

Therefore, the first option gives the correct combined inequality.

<h2>Answer:</h2>

The combined inequality that is represented by the number line is:

      x less than or equal to -4 or x greater than or equal to 3

<h2>Step-by-step explanation:</h2>
  • Number line with a closed circle on -4, shading to the left .

This means that the inequality that is satisfied is:

                      x ≤ -4

Since, shaded region to left means that all the values less than that number are covered.

Also, closed circle at a number means that that number is also included in the range and hence, the inequality will be a inequality with a equal sign.

  • closed circle on 3, shading to the right

This means that the inequality is:

                     x ≥ 3

( Since, the shading is to the right this means that all the values greater than that number is covered.

Also, closed circle at that point means that the inequality will be a inequality with a equal sign)

This is a parabola, first, locate the line of symmetry.
the line of symmetry is x=-b/2a
in this case, b=-2, a=-1, so the line of symmetry is x=-1
when x=-1, f(x)=-(-1)²-2(-1)-3=-2  
locate the point (-1,-2) on the grid. this point is the vertex.
get two pairs of points with x=-1 as the symmetry line:
(0, -3) and (-2, -3); (1,-6) and (-3,-6) 
connect these five points into a parabola, stick out at the ends because it will extend forever downward.

Multiply all terms by 15
3x+3x= 10x+30

Combine like terms
6x=10x+30

Subtract 10x from both sides
-4x=30

Divide both sides by -4
x= -7.5

Final answer: -7.5
