You can treat x and 2x+1 just as though they are real numbers.
So f(2x+1) = 3(2x+1) - 5 = 6x + 3 - 5 = 6x - 2
In the above, I made use of something called the distributive law which says that if a,b and c are real numbers, then a(b+c) = ab + ac.
Answer: x= -1.02 or -95/93 or -1 2/93
Step-by-step explanation:
The x intercepts must be 1 and -4, so C.
180 x 0.06 = 10.80; $10.80.
