Answer:
See explanation below
Step-by-step explanation:
Let's use Q10 as an example and you will work on Q11-12 as they are the same.
I believe the middle column (5x-4) wants you to substitute the given x, so:
Q10.1: 5(-2)-4
Q10.2: 5(4)-4
Q10.3: 5(0)-4
Q10.4: 5(1)-4
The right most column (f(x)) should be asking you the answers from your middle column, so:
Q10.1: -14
Q10.2: 16
Q10.3: -4
Q10.4: 1
As for the domain and range, let's define these two names in case you haven't learnt them:
Domain: What reasonable x values can be inputted into the function.
Range: What reasonable results will be shown after calculating.
In these case, you can input any real numbers into x as you like into the function, the results will always be other real numbers.
Hence, for Q10-12, D and R should be "All real numbers"
Just some extra info, Let the function f(x) be . Since the denominator cannot be 0 in a fraction, we say that the domain of x is "All real numbers except -1" as
and
is undefined.
Answer:
48:29
Step-by-step explanation:
So lets find the ratio without simplest form: the ratio is 96:58
When writing the ratio we write the one mention first
Now lets write it in simplest form practically reducing it to its lowest term
( we first write it as a fraction)
÷
=48:29
So the answer is 48:29

The generic equation of the line is:
Where,
m: slope of the line
(T0, H0): ordered pair belonging to the line.
The slope of the line is:
Substituting values we have:
Rewriting:
Then, choosing an ordered pair we have:
Substituting values we have:
Rewriting the equation:
Then, for 8 hours we have:
