so, the first thing the question asks of you is to see that f(g(x)) = x. try it out, plugging g(x) in as the x-variable in the first equation:
f(g(x)) = (∛(x - 4))³ + 4
they were merciful in writing this problem, and thankfully your cube roots cancel out and don't cause you any trouble. continue solving:
f(g(x)) = (∛(x - 4))³ + 4 ... cube root and exponent cancel
f(g(x)) = x - 4 + 4 ... simplify
f(g(x)) = x
so, yep. that one worked. try out the second half of the question: g(f(x)) = x
g(f(x)) = ∛((x³ + 4) - 4) ... simplify inside your radical, cancelling out the 4s
g(f(x)) = ∛(x³) ... the cube root of x³ is x itself, so:
g(f(x)) = x
and there you are. you've confirmed that these are inverses.

There is no solution to the equation, the sides are uneven. so, option A is correct.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given equation is;
3x − 2 = 3x + 5
Subtract 3x both sides;
3x − 2 - 3x = 3x + 5 - 3x
-2 = 5
Thus, there is no variable left in the equation.
Hence, there is no solution to the equation, the sides are uneven. so, option A is correct.

Answer:
Since the ratio of cars to SUVs is 5:2, we can assume that there are 5x cars and 2x SUVs, where x is a positive integer.
The total number of cars and SUVs is 5x + 2x = 7x.
Since there are 70 vehicles in total, we can set up the equation 7x = 70.
Simplifying the equation, we get x = 10.
Thus, there are 2x = 2 * 10 = 20 SUVs in the parking lot.

a Write the mode.
b Work out the range.
Answers
The mode of the data is 13 and 18 and range is 8.
What is mode and range?
The value that appears most frequently is the "mode." There is no mode for the list if no number on the list is repeated.
A list of numbers' "range" is just the range between the largest and lowest values. It conveys "spread," which is the degree to which the values are scattered (or how concentrated they are).
Given:
data: 16 14 13 10 13 18
Arrange the data: 10 13 13 14 18 18
a) The mode of the data is
Mode = 13 and 18.
b) Range = Highest - lowest
Range = 18 - 10
Range = 8
