Answer:
x = 
or 
Step-by-step explanation:
Let f(x) = y = 5x - 7. Then f(3) = 5(3) - 7 = 8, and f(8) = 5(8) - 7 = 33
Then the ave. r. of c. of f(x) = 5x - 7 from x = 3 to x = 8 is
33 - 8 25
----------------- = -------- = 5 (answer)
8 - 3 5
I know that one is obtuse and acute
Answer:
x = j – f - 2
Explanation:
(x + f) + 2 = j Remove parentheses
x + f + 2 = j Subtract f from each side
x + 2 = j – f Subtract 2 from each side
x = j – f - 2
