Step-by-step explanation:
Given information: AC=32, AB=2x, BC=6x+8 and point B lies between A and C.
We need to find the value of x.
(Segment addition property)
Substitute the given values.
(Substitution)
Combine like terms.
(Simplification)
Subtract 8 from both sides.
(Subtraction property of equality)
Divide both sides by 8.
(Division property of equality)
Therefore, the value of x is 3.
Answer:
See attached diagram
Step-by-step explanation:
You are given the equation of hyperbola
From this equation,
- the center of hyperbola is at point (1,-3);
- the real semi-axes
- the imaginary semi-axes
Draw two parallel lines x=1 and y=-3 (they intersect at the center of hyperbola), then on horizontal line match two hyperbola's vertices (7 units to the left and 7 units to the right from the center). Then draw two branches of hyperbola (one in negative direction and one in positive direction).
