Algebra Blizzard Bag #3 Chapter 4 Review Name ______________________________ Date ________________ Core _____ For problems 1 – 2, solve each system of equations by graphing. 1. y = 2x + 9 2. y = 1/2 x – 1 3x + 4y = - 8 2x – y = -7 For problems 3 – 8, write a system of equations to represent each problem scenario. Define the variables. Then solve the system by substitution or elimination. 3. Angles X and Y are supplementary, and the measure of angle X is 24 degrees greater than the measure of angle Y. Find the measures of angles X and Y. 4. The perimeter of a rectangle is 56 meters. The length is 4 meters longer than the width. What are the dimensions of the rectangle? 5.
