I need help plz and thank you

3x + 4y = 5 x- 3y = -7 solve by substitution

Zack notices that segment nm and segment pq are congruent in the image below: which step could him determine if δnmo ≅δpqr by sas? (5 points) segment mo ≅ segment qr segment on ≅ segment qp ∠ n ≅ ∠ r ∠ o ≅ ∠ q

An equation in slope-intersept form the lines that passes thought (-8,1) and is perpindicular to the y=2x-17.
