BaLLatris [955]

Use the Binomial expansion theorem to find and simplify each term.

$x^{18} - \frac{ 27x^{6} }{2}+ 81x^{14}- \frac{ 567x^{12} }{2}+ \frac{ 5103x^{10} }{16}- \frac{ 15309x^{8} }{16}+ \frac{ 15309x^{6} }{16} - \frac{ 59049x^{2} }{256}-$ $\frac{19683}{512}$

3x+4y=25 3x-3y=-3 Following system of equations write answer as an ordered pair

Charra [1.4K]

$3x+4y=25\\
3x-3y=-3|\cdot(-1)\\\\
3x+4y=25\\
\underline{-3x+3y=3}\\
7y=28\\
y=4\\\\
3x-3\cdot4=-3\\
3x-12=-3\\
3x=9\\
x=3\\\\
\boxed{(x,y)=(3,4)}
