otto used 5.5 cups of whole wheat flour and x cups of white flour in the recipe. what is the equation that…

Explanation:

Step1: Determine the total - flour equation

The total amount of flour $y$ is the sum of whole - wheat flour and white flour. Otto used 5.5 cups of whole - wheat flour and $x$ cups of white flour. So the equation is $y=x + 5.5$.

Step2: Analyze the constraints on $x$

The amount of white flour $x$ can be any non - negative real number because you can use a non - integer amount (like 0.5 cup) of flour in a recipe. So $x\geq0$ and $x\in R$.

Step3: Analyze the constraints on $y$

Since $y=x + 5.5$ and $x\geq0$, then $y=x + 5.5\geq5.5$ and $y\in R$.

Answer:

$y=x + 5.5$; $x$ is any real number greater than or equal to 0, and $y$ is any real number greater than or equal to 5.5. So the correct option is: $y=x + 5.5$; $x$ is any real number greater than or equal to 0, and $y$ is any real number greater than or equal to 5.5.
