Find the inverse of the matrix , if it exists

So, option A is correct.

Step-by-step explanation:

To find the inverse of the matrix, the formula is:

Inverse of the matrix exists if |A| does not equal to 0

|A| = 7 * 9 -( -2 * -10)

|A| = 63 - 20

|A| = 43

AS |A| ≠ 0

so inverse exist.

now finding Adj A

=

So, option A is correct.

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
