tavon has a gift card for $175 that loses $4 for each 30 day period it is not used. he has another gift card for $155 that loses $3.50 for each 30-day period it is not
used.
a. write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
b. what will the value of each card be when they have equal value?
can be used to find the number of 30-day periods until the values of the gift cards will be equal.
fy is the number of 30-day periods, then the equation

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.
