How do i sove a inverse matrix 3x+4y=9; 3x+y=7

idk

step-by-step explanation:

idk

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
