Answer:
using the first two equations cancelling the z
-2x-2y-5z=-7
6x+8y+5z=9
4x +6y= 2
using the second and the third equations cancelling the z
6x+8y+5z= 9
-2x-3y-5z= -6
4x +5y = 3
4x + 6y = 2
-4x -5y = -3
y= -1
2x + 2(-1) + 5z = 7
2x - 2 + 5z = 7
2x + 5z = 9
6x + 8(-1) + 5z = 9
6x - 8 + 5z = 9
6x + 5z = 17
-2x - 5z= -9
4x = 8
x = 2
2(2) + 2(-1) + 5z= 7
4 - 2 + 5z = 7
2 + 5z = 7
5z = 5
z = 1
(2, -1, 1)
the answer is a.
Step-by-step explanation:
In this case, you have to multiply each term of one parenthesis by each term in the second bracket. After receiving a number of factors need to be segregated and placed in the correct order.
Given:
initial amount deposited = $2,520
final amount acquired = $2,850
number of years = 2 years
Use the formula from economics,
F = P (1 + i)^n
2,850 = 2520 (1 + i)^ 2
solve for i
i = 6.3% per year <span />
