2. ben has a cell phone plan where he pays $12 per
month plus $.10 per minute of talk time. the equation
y = 0.10x + 12 can be used to find his monthly
phone bill y given the number of minutes x he
spends talking. which set or inequality represents a
reasonable range of the function?
f = - 15x +700
let's solve for f.
step 1: divide both sides by x.
-30 sqrt50 x^5.
= 2 sqrt 5x^3* -3 sqrt10 x^2
= -6 sqrt50 x^5
month plus $.10 per minute of talk time. the...
