Consider the equation cx 2 d 5 2x 1 4. a. Replace c in the equation with 2. For what value of d would the equation have infinitely many solutions? Explain. b. Replace d in the equation with 2. For what value of c would the equation have no solution? Explain.

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=
