Since |-4|=4 and |5|=5
from lowest to highest,
-7, 2, |-4|, |5|
Answer:
-3.1
Step-by-step explanation:
5.1 + 4.2 = 9.3
9.3/-3 = -3.1
Answer:
see explanation
Step-by-step explanation:
(a)
Substitute x = - 1 into f(x)
f(- 1) = 6 - 2(- 1) = 6 + 2 = 8
(b)
Substitute x = into g(x)
g( ) = = 9 × 3 = 27
(c)
Substitute x = f(x) into h(x)
h(6 - 2x)
= 6 + (6 - 2x)² ← expand using FOIL
= 6 + 36 - 24x + 4x² ← collect like terms
= 4x² - 24x + 42
(d)
Substitute x = f(x) into g(x)
g(6 - 2x)
=
(e)
Evaluate g(12) then substitute value obtained into f(x)
g(12) = = , then
f( ) = 6 - (2 × ) = 6 - =
(f)
Evaluate f(- 9) then substitute the value obtained into h(x)
f(- 9) = 6 - 2(- 9) = 6 + 18 = 24 , then
h(24) = 6 + 24² = 6 + 576 = 582
