The solution of the system of equations negative 3x - 4y - 3z equals -7 2 x - 6 y + 2 Z equals 3 5 x - 2 y + 5 Z equals 9(x, y, z) is
<u>Solution:</u>
Given, system of equations are
3x – 4y – 3z = - 7 ----- eqn (1)
2x – 6y + 2z = 3 ------ eqn (2)
5x – 2y + 5z = 9 ---- eqn (3)
We have to find the solution of the equations.
Now, from eqn (2)
----- eqn 4
Multiply eqn 4 with 5
Now subtract eqn 5 from eqn 3
5x – 2y + 5z = 9
5x – 15y + 5z = 15/2
(-)-----------------------------------
0 + 13y + 0 = 9 - 15/2
Now, perform eqn (1) + 3 x eqn (1)
3x – 4y – 3z = - 7
3x – 9y + 3z = 9/2
(+) -------------------------------------
6x – 13y = - 7 + 9/2
Then from eqn (4)
Hence, the solution is (x, y, z) is
Answer:
d
Step-by-step explanation:
compound interest would generate more over time then simple interest
Answer:
the answer is ( x-9) (x+1) = 0
Step-by-step explanation:
more to the solution is x= -1, 9
By Pythagorean theorem
x²+GF²=EF² ( where G is the point of intersection of perpendicular lines)
now, GF=1/2 EF= 12
x²+12²=24²
x²=24²-12²
x²=432
x=√432
x=12√3
x≈20.78
