I think the trick is to add the two middle terms together. (And the 2 end terms).
8 - 12x
The variable is x. The coefficient is - 12.
8 is a constant.
The coefficient always goes with a variable.
3x^2 + 2x + 5
Nothing can be combined. The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.
Find the unit rate:
4.5 miles 2
------------- * ------- = 9 mph
0.5 hour 2
Answer:
--- Percentage increase
Step-by-step explanation:
Given
Let
So, we have:
--- Monday
--- One month later
Required
The function
The function is represented as:
In , we have:
Rewrite as:
In , we have:
Substitute
Solve for b
Recall that:
Hence, the function is:
To get the monthly percentage increase (r), we have:
Compare to:
So:
Make r the subject
Express as percentage
The common difference is the constant rate of change, or the slope of the function. We can construct the linear function if we know the slope and the vertical intercept. To find the y-intercept of the function, we can subtract the common difference from the first term of the sequence.
