The equation y=2x+3 represents the cost y (in dollars) of mailing a package that weighs x pounds. a. graph the equation b. use the graph to estimate how much it costs to mail the package c. use the equation to find how much it costs to mail the package

the equation that represents the cost is a lineal and it is ,as you can see , it is a function with positive slope, it means that as the pounds are heavier, the shipping cost will be higher, the shipping cost is from three dollars onwards, as you can see in the graph, as there are no negative weights, the values of x are taken to from zero onwards

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
