Answer:
3/2(x+y)
Step-by-step explanation:
The cost of 2 DVD is x+y
Divide by 2 to get the cost of one DVD
(x+y) /2
Multiply by 3 to get the cost of 3
3/2(x+y)
4.6 is the correct answer. Hope I helped:)
Answer:
- T'(1, -2)
- U'(1, -1)
- V'(2, -1)
- W'(2,-2)
Step-by-step explanation:
Translation 4 right adds 4 to each x-coordinate.
Translation 4 down subtracts 4 from each y-coordinate.
Doing this arithmetic gives you the results above.
Let f(x)=y
f^-1(x)=x
y=1/(x+5) - 1
y+1=1/(x+5)
(x+5)=1/(y+1)
x=1/(y+1)-5
f^-1(x)=1/(x+1) -5
denominator cannot equals to zero
x+1≠0
x≠-1
answer
B
