- Take a handful of two types of coins, and write a problem similar to Example 5.46 relating the total number of coins and their total value. Set up a system of equations to describe your situation and then solve it.arrow_forwardSolve the system 21 X2 = I3 X4 4x₁5x₂ +3x3 +3x4 +₂ +3x3 +2x4 3x₁4x₂ +6x3 +5x4 -2x₁ +2x₂ +63 +4x4 -I1 +8 +t - - || = 0 1 1 2arrow_forwardCompute the discriminant of each equation in Exercises 83-90. What does the discriminant indicate about the number and type of solutions? 83. x - 4x - 5 = 0 85. 2x - 11x + 3 = 0 87. x = 2x - 1 89. x? - 3x - 7 = 0 84. 4x? – 2x + 3 = 0 86. 2x? + 11x - 6 = 0 = 2x - 1 90. 3x + 4x- 2 = 0 88. 3x2arrow_forward
- In Exercises 7–10, determine the values of the parameters for which the system has a unique solution, and describe the solution. 7. 6sx1 + 4x2 5 9x + 2sx₂ = -2 =arrow_forward7. Use the inverse found in Exercise 1 to solve the system 8x1 + 3x2 = 2 5x1 + 2x2 -1 =arrow_forwardSolve the system 21+52₂-23 đi thông 00000 +5x5 +4x6 = 0 -24 +225 -3x6 = 9 -725 +6x6 = 000000 +t 000000 +u ¯¯¯¯¯¯arrow_forward
