Question

Solve this system of equations:
A + B + C + D + E + F + G + H + I + J = 76.5
2A - 6B + C + (3/2)D - (1/2)E - F + G + 2H - 50I - 12J = -9
-A - 4B + 11C - 7D + 6E - (3/4)F - 3G - 3H + (1/2)I - (7/2)J = -261.75
32A - B + C + D - 22E +22F - 22G - 7H - I + 3J = -278.5
-(5/4)A + 3B - 5C - 4D + E - (1/2)F + G + 2H + 7I - 44J = 150.5
4A + B - C + D - 6E + 13F - 4G - H + 12I + 8J = 99
9A + 12B + 41C - 200D + 69E - 81F + 11G - 5H - 120I + 500J = -516
-A - 2B - 8C + (20/3)D - E - 12F - 5G - 2H - (2/3)I - 33J = -66 - 2/3
5A - 16B -3C + 3D - 5E - 5F - 7G + 3H - I - 2J = 30

Answer 1

What are you allowed to use? Graphing calculators? Computer softwares? This seems to tedious to solve by hand.

Answer 2

No way you have this question on Odysseyware

Answer 3

Yeah ok cause your on the final exam

Answer 4

)x^9-5x^6+3x^3+1
this is factor able
find the value of a^5+b^5+c^5
in the equation

Answer 5

For reall

Answer 6

Is this correct?
\[
\begin{align*}
A+B+C+D+E+F+G+H+I+J&=76.5\\
2A-6B+C+\frac{3}{2}D-\frac{1}{2}E-F+G+2H-50I-12J&=-9\\
-A - 4B + 11C - 7D + 6E - \frac{3}{4}F - 3G - 3H + \frac{1}{2}I - \frac{7}{2}J &= -261.75\\
32A - B + C + D - 22E +22F - 22G - 7H - I + 3J &= -278.5\\
-\frac{5}{4}A + 3B - 5C - 4D + E - \frac{1}{2}F + G + 2H + 7I - 44J &= 150.5 \\
4A + B - C + D - 6E + 13F - 4G - H + 12I + 8J &= 99\\
9A + 12B + 41C - 200D + 69E - 81F + 11G - 5H - 120I + 500J &= -516\\
-A - 2B - 8C + \frac{20}{3}D - E - 12F - 5G - 2H - \frac{2}{3}I - 33J &= \frac{196}{3}\\
5A - 16B -3C + 3D - 5E - 5F - 7G + 3H - I - 2J &= 30\\
\end{align*}
\]

Answer 7

F u. How the hell are you suppose to solve this sh!t?

Answer 8

like this



(Given indirectly to reduce accidental cheating.)
A = 6 - 4 + 27 - 12 - 20 + 7/2 + 10 - (1/2)*21
B = 2 - 5 + 22 - 4 - 19 + 37 -16
C = -5 -4 + 17 + 22 - 30 + 3/2 + 10 - 33/2
D = 10 - 6 + 37 - 44 - 12 + 31 -12
E = 100 - 33 - 44 + 150 - 88 + 25 - 73 - 35
F = 56 - 74 + 106 - 82 + 69 - 77
G = 57 - 31 - 43 + 79 - 29 - 43
H = 3 + 5 - 2 + 13 - 67 + 2 - 4 + 23 - 71 + 156 + 11
I = 7/2 + 44 - 7 - 24 + 26/2 - 12 - 17
J = 3/4 + 12/16 + 123 -77 -64 - 3/2 + 19

t = 5492 - 3902 - 2639 + 1678 - 506

Answer 9

I would use a graphing calculator the find the row reduced echelon form of the augmented matrix. I definitely won't do this by hand.

What is your question? Don't give me a system of linear equations with 150! variables.
