Step-by-step explanation:
The systems of equations are
Let us assume the rate of the current be c
Now actual speed against the current is (15 - c)
And, the actual speed with the current is (15 + c)
Here we applied the time formula i.e. distance by speed
Also the upstream time - downstream time = 4
Now the equations are
This means which transformation makes the same answer at x = 0
f(x) = 3x + 4
f(0) = 4
g(0) = 1 - 1 = 0
Which transformation makes 4 = 0?
4 + x = 0 + y
4 - 3 =0 + 1
1 = 1
Option 1 is your answer
f(x) = 3x + 4
f(0) = 4
g(0) = 1 - 1 = 0
Which transformation makes 4 = 0?
4 + x = 0 + y
4 - 3 =0 + 1
1 = 1
Option 1 is your answer
