4. 22
Step-by-step explanation:
1.
2.
Where a is the side
We are given an area o square =
So,
4. We are given that the solution of quadratic equation -9 and 9
So, equation becomes:
So, in the given equation
z should be the number from which if we subtract 103 so we get 81
Substitute z = 22
Thus the value of z is 22
Option 3 is the correct answer. The missing values of (x, y) is (8, 20).
<h3>How do you find out the values?</h3>Given that the function is,
The function is a linear equation that can be solved graphically. The values of both variables x and y can be found on different points along with the straight-line graph.
Also, for every value of x, there is a corresponding value of y.
For the given options, we put the values of x to find the corresponding value of y.
For option 1, put x = 0 in the given function,
But for x=0, y= 18, hence option 1 is not correct.
For option 2, put x = 5 in the given function,
But for x=5, y= 19.5, hence option 2 is not correct.
For option 3, put x = 8 in the given function,
But for x=8, y= 20, hence option 3 is the correct answer.
Hence we can conclude that option 3 is the correct answer. The missing values of (x, y) is (8, 20).
