Im not 100% sure but im pretty sure you are right brother! God bless...Good luck!
Step-by-step explanation:
given :
2x - 3y = 11
-6x + 8y = 34
find : the solutions of the system by using Cramers Rule.
solutions:
in the matrix 2x2 form =>
[ 2 -3] [x] [11]
=
[-6 8] [ y] [34]
D =
| 2 -3 |
|-6 8 |
= 8×2 - (-3) (-6)
= 16-18 = -2
Dx = | 11 -3 |
| 34 8 |
= 11×8 - (-3) (34)
= 88 + 102
= 190
Dy = | 2 11 |
|-6 34 |
= 2×34 - (-6) (11)
= 68 + 66
= 134
x = Dx/D = 190/-2 = -95
y = Dy/D = 134/-2 = -67
the solutions = {-95, -67}
Answer:
6 cm. triangles have 3 sides, and total length is 18 cm. divide 18 by 3 equal sides to get 6 cm
Answer:
the answer is 7
Step-by-step explanation:
2x-y
2*5 - 3
10 - 3
7
18 * 100 / 36 = 200
