Determine if the statement "The sum of the interior angles of a 1uadrilateral is 360 degrees." is always, sometimes, or never true.

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
