A+b=2 and ab=-48, let a=x and y=b
x+y=2 implies y=2-x
xy=-48 implies x(2-x)=-48
so 2x-x^2+48=0
Answer: Yes, you can tell how to model real life relationships. For example, a linear function is written at y=mx+b. Y is the total value, b is initial value, and m is the slope of the function.
Step-by-step explanation:
Real life example:
Your school needs to raise money. To do this, they host a school dance! The admission is $5 (initial cost, b), plus an additional $3 dollars for drinks. 3 would be the slope per drink, so this can be represented by y=3x+5!

An irrational number is a number that can't be written as a simple fraction while a rational number is a number that can be written as the ratio of two integers, that is, as a simple fraction. So in this case we have the number 2 which is ration, and we can multiply it by an irrational number 
such that the product is an irrational number. So any irrational number will meet our requirement because the product of any rational number and an irrational number will lead to an irrational number. For instance:
