Answer:
The provided statement
is true in the domain of real number.
Step-by-step explanation:
Consider the provided information.
Any equation or inequality with variables in it is a predicate in the domain of real numbers.
The provided statement is:

Here, we need to find the value of x for which the above statement is true.
Since the value of x can be any real number so we can select the value of x as √5
(√5)²-4=1
5-4=1
Which is true.
Thus, the provided statement
is true.
Answer:

Step-by-step explanation:
Consider the real number y such that f ⁻¹(x) = y

We need to find y in order to determine the expression of f ⁻¹(x)
f(y) = x ⇔ -2y + 4 = x
⇔ 4 - x = 2y
⇔ y = (4 - x)/2

X - 1 + x + x + 1 = 345
Consecutive means that each member differs by one. Put another way you add one to the previous number to get the next number.
3x = 345
x = 115
x - 1 = 114
x + 1 = 116
Due to the circular shape, one complete rotation of the flag is equal to the circumference of a circle with radius 12 ft.
Then, use the following formula for the cirumference:
C = 2π·r
where r is the radius. In this case, r = 12 ft and π = 3.14. Replace the previous values into the formula for C:
C = 2(3.14)(12 ft)
C = 75.36 ft
Hence, the flag has to travel 75.36 ft to complete a full rotation
