-3x+y+z=-1, 2x+y-z=-4, x-y+z=7 getting sums -x+2y=-5, 3x=3, from the second we can easily see: x=1, which makes -x+2y=-5 become: -1+2y=-5, 2y=-4, y=-2, making x-y+z=7 become: 1--2+z=7 1+2+z=7, z=4 So the solution to the system of equations is: (1,-2,4)
Solve: 25 points find the fifth term of an increasing geometric progression if the first term is equal to 7−3 √5 and each term (starting with the second) is equal to the difference of the term following it and the term preceding it.
Drag each number to the correct location on the statements. not all numbers will be used. consider the sequence below. -34, -21, -8, 5, complete the recursively defined function to describe this sequence
