QwPLEASE HELP WITH MY TEST IT"S SO HARD HELP Paul is comparing the cost of cell phone services. At CellCoA, the phone he wants costs $305 and the unlimited calling plan costs $45 per month. At CellCoB, Paul can purchase the same phone for $350 and get an unlimited calling plan for $30 per month. In how many months will both plans cost the same?

These equations, which are graphed below, represent the situation.

y = 45x + 305

y = 30x + 350

Here, x represents the number of months and y represents the amount paid.

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)
