Walter wants to solve the given system of linear equations. X+ 2y = 9
6x - y = 2
His method is to replace the second equation with an equivalent form so that he can eliminate one of the variables by adding the equations tog
rewrites the system of equations as follows:
x + 2y = 9
12x - 2y =
What number should go in the blank space, in order for this system of equations to produce the same solution as the original system?

Which system of linear inequalities is represented by the graph?

Find the values of the variables in the kite

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.
