Susan is looking into a new cell phone carrier. she researches her options and finds the two companies which off the best reception in her neighborhood offer very different monthly plans. write a function rule which represents each company’s monthly fees. a) company a offers unlimited minutes and texts for a flat fee of $50 per month and charges $1.50 for each gb of data used per month. b) company b offers unlimited minutes and texts for a flat fee of $35 per month and charges $5.00 for each gb of data used per month.

Let x represent the number of GB of data used per  month .Let f(x)  be the function that represents the total cost .

A) For Company A it is given :Company A offers unlimited minutes and texts for a flat fee of $50 per month and charges $1.50 for each GB of data used per month. Charge for x GB data used = 1.50x.

Total cost f(x)= 1.50x+50

B) Given :Company B offers unlimited minutes and texts for a flat fee of $35 per month and charges $5.00 for each GB of data used per month.Cost of x GB data = 5x

Total cost f(x)=5x+35.

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
