Answer:
134
Step-by-step explanation:
1. seperate the rectangle bottom and the triangle top
2. I did the triangle first: 4×12=48÷2=24
3. the rectangle: 11×10=110
4. add the final numbers together: 110+24=134
Answer:30
Step-by-step explanation: act like both of the triangles are there, that is a rectangle 6 times 10 equals 60. 60 divided by 2 is 30
Answer: f^{-1}(x) = 3-x/3
Step-by-step explanation: Let y = f(x) and rearrange making x the subject, that is...
1. y = - 3x + 3 ( add 3x to both sides )
2. 3x + y = 3 ( subtract y from both sides )
3. 3x = 3 - y ( divide both sides by 3 )
4. x = 3-y/3
Change x back into terms of y
f^{-1}(x) = 3-x/3
Parallel line means the same slope
（8-1）/(-17-a)=(1-5)/(a+2)
so a is 18
