Answer:
Explanation:
f(3) = (3 - 1) • 3/2
f(3) = 2 • 3/2
f(3) = 3
f(4) = (4 - 1) • 3/2
f(4) = 3 • 3/2
f(4) = 9/2
f(5) = (5-1) • 3/2
f(5) = 4 • 3/2
f(5) = 6
f(6) = (6-1) • 3/2
f(6) = 5 • 3/2
f(6) = 15/2
f(7) = (7-1) • 3/2
f(7) = 6 • 3/2
f(7) = 9
Answer:
it has to be 45%
Step-by-step explanation:
Find out what part (fraction) of the choir's members are men. That is 18/40, or 9/20. Write 9/20 as a percent. Use equivalent fractions: 9/20 = 45/100 = 45%.
Answer:
It will be 6:10
Step-by-step explanation:
Answer:
Replacing the value or x = -3in 7 - 2x, we get,
7 - 2 x (-3)
= 7 + 6
= 13
Plug in 2 for x
f(2) = (2-2) (2+2)
= (0)(4) = 0
f(2) = 0
