Answer:
y is equal to 24
Step-by-step explanation:
If y is directly proportional to x when x is equal to 5 and y is 12, then when you multiply 5 by 2 which is 10, y will be proportional to that when you multiply 12 by 2 which is 24
Answer:
The rate of change of f(x) is greater than that of g(x)
They have the same y intercept of 14
Step-by-step explanation:
Given

Table for function f(x)
Required
Compare their rate of change and intercept
For g(x), we have:

The form of an equation is:

Where


So:


For f(x): Start by calculating the slope (m)



The intercept is calculated using:

Where

--- we want to solve for y
So:


Multiply both sides by 2

Make y the subject


So, we have:
and
-- for g(x)
and
--- for f(x)
By comparison:
The rate of change (i.e. slope) of f(x) is greater than that of g(x) because 
They have the same y intercept of 14
Answer: (i) A = 2500 (
(ii) A =$ 4,974.47
Step-by-step explanation:'
The exponential function is given as :
A = P
Where :
A = amount
P = principal
r = rate %
n = number of years
substituting , the exponential function to model the situation becomes
A = 2500 (
(ii) when n = 20 , the Amount becomes
A = 2500(
A =$ 4,974.47
They would all equal to 91..for question 26 and 27 i cont really figure out give me a min
