I need to solve these two equations using either substitution or elimination 1/4x - 1/2 = 5
3x + 2/3y = -40

If g(x) is an odd function, which function must be an even function?

Jabari is power washing houses for a summer job. for every job, he charges an initial fee plus $30 for each hour of work. his total fee for a 4 -hour job, for instance, is $170 . jabari's total fee,f, for a single job is a function of the number,t, of hours it takes him to complete the job. write the function's formula.

Just tell me how to set up the equation.
