Answer:
(1, - 8 )
Step-by-step explanation:
Given that P'( - 6, - 4 ) is the image of P(- 2, 3 )
Then the rule is (x, y ) → (x - 4, y - 7 )
Thus
A(5, - 1 ) → A'(5 - 4, - 1 - 7 ) → A'(1, - 8 )

<span>A freight train completes its journey of 150 miles 1 hour earlier if its original speed is increased by 5 miles/hour. What is the train’s original speed?
***
let x=original speed
x+5=increased speed
travel time=distance/speed
..
lcd:x(x+5)
150(x+5)-150x=x(x+5)
150x+750-150x=x^2+5x
x^2+5x-750=0
(x-25)(x+30)=0
x=25
What is the train’s original speed? 25 mph</span>
The sentence describing the scale of the model is 1 m represents 40m.
Given,
The length of the ship = 120 m
A scale model of the ship is made.
The length of the model = 3 m
We have to find that, 1m in model represents how much meter of the original.
Scale model;
A physical model that is geometrically similar to an object is called a scale model (known as the prototype). Scale models may be larger than small prototypes like anatomical structures or subatomic particles, but they are often smaller than huge prototypes like cars, buildings, or people.
Here,
Original ; scale model
120 ; 3
That is,
120/3 = 40
Therefore,
1 meter in scale model represents 40 m of the original ship.

Answer:
Total songs = 15
Liked songs = 3
Un liked songs = 15-3=12
Find the probability that among the first two songs played
(a) You like both of them.
Probability that among the first two songs played you like both of them = 
(b) You like neither of them.
Probability that among the first two songs played you like neither of them = 
(c) You like exactly one of them.
Probability that among the first two songs played you like exactly one of them = 
(d) Redo (a)-(c) if a song can be replayed before all
(a) You like both of them. Would this be unusual?
Probability that among the first two songs played you like both of them = 
(b) You like neither of them.
Probability that among the first two songs played you like neither of them = 
(c) You like exactly one of them.
Probability that among the first two songs played you like exactly one of them =
