Answer:
x= -2
y=0
z= 1
Step-by-step explanation:
{-x+5y-10z=-8
2x-y+10z=6}
{2x-y+10z=6
-7x-3y-10y=4}
{-x+5y-10z=-8
2x-y+10z=6} = x+4y=-2
{2x-y+10z=6
-7x-3y-10y=4} = -5x-4y=10
{x+4y=-2
-5x-4y=-10}. =. y= 0 x= -2
substitute x and y in -x+5y-10z=-8
-(-2)+5(0)-10z=-8
solve for z
z= 1
(x,y,z) = (-2,0,1)

Recall that for |<em>x</em>| < 1, we have
Differentiating both sides gives
and multiplying both sides by 8 gives the series for <em>f(x)</em> :
and this converges over the same interval, |<em>x</em>| < 1, so that the radius of convergence is 1.
A quart is one half of a quart and a half is half of a gallon. A gallon is four quarts.
