STEP-BY-STEP SOLUTION:
( x + 4 )^2 + y^2 = 22
x^2 + 2 × x × 4 + 4^2 + y^2 = 22
x^2 + 8x + 16 + y^2 = 22
y^2 = 22 - x^2 - 8x - 16
y^2 = - x^2 - 8x + 6
FINAL ANSWER:
Therefore, the answer is:
D. y^2 = - x^2 - 8x + 6

Given:
The matrix is ![[-8]](https://tex.z-dn.net/?f=%5B-8%5D)
.
To find:
The determinant of given matrix, i.e, 
.
Solution:
If a matrix is A of order 
, then the value of the determinant of that matrix is equal to the element of that matrix.
For example: Let A be the matrix of order .
![A=[a]](https://tex.z-dn.net/?f=A%3D%5Ba%5D)
Then,
The given matrix is . So, the determinant of given matrix, i.e, , is
Therefore, the value of determinant of given matrix is -8.
Answer:
Step-by-step explanation:
<u>Points given:</u>
<u>Partition ratio: </u>
<u>Formula for the point:</u>
- x = x1 + a/(a+b)×(x2 - x1)
- y = y1 + a/(a +b)×(y2 - y1)
<u>So the points are:</u>
- x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5
- y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2
