Answer:
Step-by-step explanation:
When matching graph to inequality, the first things to look for are the nature of the boundary line (solid or dashed), and the direction of shading relative to the boundary line (above or below, left or right).
<h3>Boundary line</h3>
The boundary line of the solution set of an inequality will be solid if the line is <em>included</em> in the solution. That is, the inequality will include the "or equal to" case. The corresponding inequality symbols are ≤ or ≥.
The boundary line of the solution set will be dashed if the line is <em>not included </em>in the solution. The corresponding inequality symbols are < or >.
<h3>Shading</h3>
The shading will be above the boundary line if the solution set includes larger y-values than those on the boundary. This will be the case when the inequality is of the form y > ( ) or y ≥ ( ).
For inequalities of the form y < ( ) or y ≤ ( ), the shading will be below the boundary line.
Similarly, the shading for an inequality of the form x > ( ) will be right of the boundary line, where x-values are greater. For inequalities of the form x < ( ), the shading will be to the left of the boundary line.
<h3>Application</h3>
In the given graph, both boundary lines are solid, so both inequalities will include the "or equal to" case. This eliminates choices A, B, D.
The shading is above the quadratic boundary line, and below the linear boundary line, so the inequalities can be expected to be of the forms ...
These forms match choice C:
The answer is 31 yards because you cant move negatively
Given that
∠ABC and ∠CBD are complementary
Sum of complementary angle = 90°
⇒ m∠ABC + m∠CBD = 90°
⇒ 25° + m∠CBD = 90° [ Given that m∠ABC = 25°]
⇒ m∠CBD = 90° - 25°
⇒ m∠CBD = 65°
Hence proved
