Please help The total monthly cost, T(m), of Teresa's cell phone plan, in dollars, is calculated using the function T(m) = 59.95 + 0.15m, where m is the
number of minutes she uses each month. The total monthly cost, R(n), of Randy's cell phone plan, in dollars, is calculated using the
function R(n) = 29.95 + 0.35n, where n is the number of minutes he uses each month. Teresa used 406 minutes last month. Randy used
327 minutes last month. How much less did Teresa owe than Randy?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
