2x1 + 4x2 + 3x3 = 4
3x1 + x2 − 2x3 = −2
4x1 + 11x2 + 7x3 = 7

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Formulate alisha has a number in mind. if she adds three to her number the result is less than five. use this information to write and solve an inequality about alisha's number. then graph the solution set.

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?
