Answer:
BD = 8.5 units
Step-by-step explanation:
From the figure attached,
ΔABC and ΔADB are the right triangles.
By applying mean proportional theorem,
BD² = AD × CD
BD² = 6 × 12
BD = √72
BD = 6√2
= 8.485
BD ≈ 8.5 units
Therefore, measure of segment BD will be 8.5 units.
Answer:
see the explanation
Step-by-step explanation:
<u><em>Verify each case</em></u>
Part 1) The graph show two identical lines, then the system has infinitely many solutions
Part 2) The graph show two perpendicular lines.
Remember that the solution of the system is the intersection point both graphs
The intersection point is (2,6)
therefore
The system has one solution at (2,6)
Part 3) The graph show two intersecting lines at (-6,-2)
Remember that the solution of the system is the intersection point both graphs
The intersection point is (-6,-2)
therefore
The system has one solution at (-6,-2)
