Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x
Answer:
Step-by-step explanation:
The area of a circle is given by :
Where
r is the radius of the circle.
If we talk about the area of half of the circle, it means we have to half the area such that,
Hence, this is the required solution.

Answer:
x≥0
Step-by-step explanation:
The arrow is moving right, to the larger numbers from the starting point at 0. This means that x has to be greater than 0
Because the point at 0 is an empty white dot, it means that it is a 'greater than or equal to' symbol ( looks like this ≤ or ≥, depending on which side you write the x)
So, the final answer is x is greater than or equal to 0, which in maths terms looks like this x≥0, or this 0≤x.
NOTE:
- filled in dot on the number line = greater than, or less than (>)
- empty dot on number line [like the one on this Q] = greater than or equal to, or less than or equal to (≥)
