Answer:
150
Step-by-step explanation:
30+60n=30+120=150
= 5+ (5x+20)<20
5x +25<20
5x< -5
x< -1
Answer:
y = (x - 1) / 2 (First answer choice)
Step-by-step explanation:
1) Start with f(x) = 2x + 1
2) Replace f(x) with y: y = 2x + 1
3) Interchange x and y: x = 2y + 1
4) Solve this result for y: 2y = x - 1, or y = (x - 1) / 2 (This matches the first
answer choice.)
