Answer:
83 points
Step-by-step explanation:
-The formula for average is given as:

Let a be his 5th score and (a+4) of the 6th
#We subtract the sum of the first 4 tests from the 6, to get the sum of the 5th and 6th tests:

Discussion:
For every value of x, g(x) = f(x) -1 meaning that the y-value of g(x) is 1 less than the corresponding y value of f(x). So the graph of g(x) is "below" f(x) or it is translated 1 unit downward from f(x)

Answer:
n<1
Step-by-step explanation:
4n−5<−1
Add 5 to both sides.
4n−5+5<−1+5
4n<4
Divide both sides by 4.
4n/4<4/4
n<1
