Can someone answer question number 39. for me. this is for 7th grade summer math and i sadly just don't get it.

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
