Can someone help plz Consider each of the scenarios below. If initial values were provided for each scenario, which could be modeled by an equation of the form Y = ax + b ? Select all that apply.

A- A Savings Account, which earns no interest, receives a deposit of $500 per month.

B- The value of a car depreciates by 10% every year.

C- Every week, 3/5 of a radioactive substance remains from the beginning of the week.

D- A liter of water evaporates from a swimming pool every day.

E- Every 8 hours, half of a drug dosage remains in the body.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7

hope it : ( : )
