Write YES if each equation below is Linear Equation in two variables, otherwise, NO. ___1. 4x - 2y = 1
___2. 6x² + 4y = 8
___3. m - 1n/2 = -8
___4. 1/y = 5
___5. 2x - 3y + 7 = 0
___6. 2a + 5 = 0

Please explain if possible, thank youu! :)

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
