If you drew a horizontal line on the coordinate plane, what could you say about the y-coordinate for every point on the line?

1 answer:

Answer: 2(x+y)-25

Step-by-step explanation:

First, we need to show the sum of Roger and Olivia's heights. If Roger is x and Olivia is y, the sum is <em>x+y</em>

Next, we need to double that. To double something we multiply it by 2. Since we need double the expression we found above, we put it in parentheses. So the doubled sum is shown as <em>2(x+y)</em>

Finally, we need to show that Isabella is 25 centimeters shorter than the doubled sum. To do that, subtract 25.

The final expression for Isabella's height is 2(x+y)-25
