Answer:
C. The mean will increase and ty e median will remain the same.
F ( x ) = - x² + 5 x + 4
between x = 3 and x = 5:
f ( 3 ) = - 3² + 5 · 3 + 4 = - 9 + 15 + 4 = 10
f ( 5 ) = - 5² + 5 · 5 + 4 = - 25 + 25 + 4 = 4
Average rate of change:
( 4 - 10 ) / ( 5 - 3 ) = - 6 : 2 = - 3 feet / sec
Solve : 9x-14 = 0
Add 14 to both sides of the equation
9x = 14
Divide both sides of the equation by 9:
x = 14/9
The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.
Its one solution because it is 1
