Zachary purchased a computer for $1,200 on a payment plan. seven months after he purchased the computer, his balance was $500. eight months after he purchased the computer, his balance was $400. what is an equation that models the balance y after x months

What is the size of the matrix resulting from

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
