Answer:
1. 19*10^8
2. B, C, D
the number has to be between 1-10 . it cannot be greater
Answer:
150x, (x<=3)
225+75x, (x>3)
*x is the number of nights stayed.
Step-by-step explanation:
-Let the number of days stayed be x.
#If the number of days is equal to or less than 3 days, the cost is:

Hence, the cost for x>3 is given by 150x
#If the number of days is greater than 3, the the cost is calculated as:


We sum the two costs for x>3

Hence, the cost for x>3 is given by 225+75x
Answer:
833.29
Just work it out on a piece of paper.
The opposite of |3| = - |3|
What is Modulus Function?
Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
- If x is positive, then f(x) = x
- If x = 0, then f(x) = 0
- If x < 0, then f(x) = -x
Given data ,
Let the number be x
x = |3|
Now , the opposite of the number x = -x
So ,
The opposite of |x| = -|x|
And ,
The opposite of |3| = - |3|
Hence , The opposite of |3| = - |3|
