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.)

GenaCL600 [577]
1 Expand
1.4t-0.4t+1.24=5.8

2 Simplify 1.4t-0.4t+1.241.4t−0.4t+1.24 to t+1.24t+1.24
t+1.24=5.8

3 Subtract 1.241.24 from both sides
t=5.8−1.24

4 Simplify 5.8-1.245.8−1.24 to 4.564.56
t=4.56
