zx1 -4x4 = -10 3x2 + 3x3 = 0 x3 + 4x4 = -1 -3x1 + 2x2 + 3x3 + x4 = 5 [1 h -5 2 -8 6] Two matrices arc row equivalent if they have the same number of rows. Elementary row operations on an augmented matrix never change the solution set of the associated linear system. Two equivalent linear systems can have different solution sets. A consistent system of linear equations has one or more solutions.

Lesson 8: Linear Systems Unit Test Algebra 2 A Unit 4: Linear Systems 26 What is the minimum value for z -3x - 1y over the feasibility region defined by the constraints shown above? o-4 o-3 7. A candy store makes a 9-pound mixture of gummy candy, jelly beans, and hard point) candy. The cost of gummy candy is $2.00 per pound, jelly beans cost $3.00 per pound, and hard candy costs $3.00 per pound. The mixture calls for two times as many gummy candy pieces as jelly beans. The total cost of the mixture is $23.00. How much of each ingredient did the store use? o3 lbs. gummy candy, 2 lbs. jelly beans, 4 lbs, hard candy o4 lbs. gummy candy, 2 Ibs. jelly beans, 3 lbs. hard candy o4 lbs. gummy candy, 3 Ibs. jelly beans, 2 lbs. hard candy 2 lbs. gummy candy, 3 Ibs. jelly beans, 4 lbs. hard candy 8.
