Answer:
x can be any number lower than -29, for example 30, which will turn into -30 because of the negative symbol before x.
Answer:
4 + 1 + 20 + 100 = 1000
5 + 20 + 100 = 1000
25 + 100 = 1000
125 = 1000
The equation would be false because 125 does not equal 1000

Choice D is true. It is just another way to write the given function.
To confirm choices A through C, replace x as follows and do the math:
For A, let x = -3. Does it really yield -11?
For B, let x = 0. Does it really yield 5?
For C, let x = 1/2. Does it really yield 4?
Take it from here.
Let the age of Jay be x years, so age of Jay's father is 2x years .
After 20 years,
Jay's age will be 
And Jay's father age will be 
But at that time, jay's age will be
So we have
Cross multiplication
Therefore Jay's age is 20 years and Jay's Father's age is 40 years .
