You are choosing between two cell phone plans. the first plan charges.24 a minute. the second charges $34.95 a month plus .11 cents a minute. if t is the number of minutes you talk and c1 and c2 are the costs in dollars of the first and second plans, give an equation of each in terms of t and then find the number of talk minutes that would produce the same cost for both plans. finally, how long would you have to talk for the two plans to have the same cost.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
