Answer:
Option B.
Step-by-step explanation:
The given quadratic equation is
We need to find the solution of given quadratic equation.
Divide both sides by 9.
Taking square root on both sides.
The solution of given equation are 
and 
.
Therefore, the correct option is B.
Answer:
Dilations.
Step-by-step explanation:
A dilation does not preserve congruency since the post-image will be of a different size than the pre-image.
Answer:
(3,5)
∧
this is x number
Step-by-step explanation:
the x number is left and right movement. if you move 3 units left you would subtract 3 from the x number. so 6-3=3 and you don't have to do anything on the y value because you don't move it.
Answer:
Aircraft carrier speed = 4.97 km/h
Step-by-step explanation:
Given that the time taken by the aircraft = 5 hours
Let the distance covered = X
Speed = V
Time taken by the ship = 7 hours
Let the distance covered = Y
Speed = 8V
Since it is 8 km/h faster than the aircraft carrier.
Using the speed formula
Speed = distance/time
Distance = speed × time
For the aircraft;
X = 5V
For the ship:
Y = 7 × 8V = 56V
Since they are 303km distance apart,
X + Y = 303
5V + 56V = 303
61V = 303
V = 303/61
V = 4.97 km/h
Aircraft carrier speed = 4.97 km/h
To find the original cost, divide the price he sold it for by the percentage:
5000 / 0.60 = 8,333.33
He bought the car for $8,333.33
