Which system of inequalities is shown in the graph?

  B.

Step-by-step explanation:

The slope of the line is positive, eliminating choice A.

The shading is below both boundary lines, eliminating choices C and D.

Choice B correctly identifies the inequalities on the graph.

The line has a slope = rise/run = 2/1 = 2. Its y-intercept is -2.

The quadratic has zeros (x-intercepts) at x=0 and x=3, so factors as x(x -3) and expands to x^2 -3x. When the shading is below the curve, the inequality will be of the form y ≤ ( ). That is, y-values in the solution set will be less than or equal to those on the curve.

Yes, she could be considered similar to herself at 6 months of age.

In mathematics, the concept of similarity is about proportion relationships. In this problem, we are discussing the relationships between age, height and diameter. We are not discussing the absolute value of the numbers themselves.

For example in Geometry, a very small triangle can be similar to a very large triangle if all the angles of the triangle are congruent. The size doesn't matter.
