The cost of an lcd tv dropped from $675 in 2012 to $475 in 2014. () find the unit rate at which the cost has been decreasing (express your answer rounded correctly to the nearest centl) dollars per year (ii) construct a linear model to predict the cost of an lcd tv and use it to predict the cost of a tv in 2016 (express your answer rounded correctly to the nearest centl) dollars note: you can earn partial credit on this problem.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

answer: 1+1

step-by-step explanation: 1+1 is at least 2
