Answer:
Step-by-step explanation:
Given
Represent
3-point word with T;
2-point with U and
1-point with V
--- (1)
If total questions is 30, then
--- (2)
If total points is 55, then
--- (3)
Substitute 5 + V for U in (2) and (3)
--- (2)
---- (4)
--- (3)
Divide through by 3
---- (5)
Subtract (5) from (4)
Recall that:
Substitute 10 for V in (5)
Answer:
Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of
Step-by-step explanation:
Function A:
Function B:
Required
Which has a greater rate of change
The rate of change of function A is calculated as thus:
Where:
So, we have:
For function B
The general function is:
Where
m is the rate of change
By comparing to
So, we have that:
Function A has a rate of -5; function B has a rate of -4.5.
By comparison: -4.5 is greater than 5
Hence, function B has a greater rate.
