Question

Determine the value of yy, if xx is 11. y equals x squared minus 5.

Answer 1

To find the value of yy when xx is 11, substitute xx into the equation y = x² - 5. The value of yy is calculated as 116 by squaring 11 and subtracting 5 from the result.

Step-by-step explanation:

The student asks to determine the value of yy if xx is 11, and provided a formula where y equals x squared minus 5. To find yy, we need to substitute xx (which is 11) into the given equation.

Here are the steps to solve for yy:

1. 
   
3. Start with the given equation: y = x² - 5.
4. 
   
6. Substitute x with 11: y = (11)² - 5.
7. 
   
9. Calculate the square of 11: 11² = 121.
10. 
    
12. Subtract 5 from 121: 121 - 5 = 116.
13. 
    
15. So, yy equals 116.

Therefore, the value of yy is 116 when xx is 11.
