Prove the segments joining the midpoint of consecutive sides of an isosceles trapezoid form a rhombus.
Find the coordinates of midpoint D.

A: (–2a – 2b, c)

B: (2a – 2b, –c)

C: (–a + b, –c)

D: (–a – b, c)

7x+8y=-18, 4x-9y=-3 solve the system of equations

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
