Answer:
(3,5),(3,1),(5,7)
Step-by-step explanation:
Answer:
- 3 and 3
Step-by-step explanation:
To evaluate (u ○ w)(- 1), evaluate w(- 1) then use this value to evaluate u(x)
w(- 1) = (- 1)² + 2 = 1 + 2 = 3, then
u(3) = - 3
---------------------------------------------------
To evaluate (w ○ u)(- 1), evaluate u(- 1) then use this value to evaluate w(x)
u( - 1) = - (- 1) = 1, then
w(1) = 1² + 2 = 1 + 2 = 3
Step-by-step explanation:
PART A
a=total amount
c=cans of oil
g=gasoline
a=2.65g+3.45c
PART B
a=2.85(8.4)+3.15(6)
a=23.94+18.90
a=42.84
Hope that helped =)
