Determine the number of solutions for the system of equations y=2/3x+4 and y=2/3-x2

Phoenix [80]

2/3x+4=2/3-2x

2/3x-(-2x)

2/3x+2x

2 2/3x+4=2/3

2/3-4=-3 1/3

2 2/3x=-3 1/3

(3 1/3)/(2 2/3)=1 1/4

x = 1 1/4

y=2/3-2x

y=2/3-2(2/3)

y=2/3-4/3

y=-2/3

The answer is (1 1/4, -2/3)

Simplify (-6^1/3)^(-2)=

Vlad1618 [11]

For this case we must simplify the following expression:

( $(-6 ^ {\frac {1} {3}}) ^ {- 2}$

So, by definition of power properties we have:

$a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Then, rewriting the expression:

$\frac {1} {(- 6 ^ {\frac {1} {3}}) ^ 2} =\\\frac {1} {(- 6 ^ {\frac {1} {3}}) * (- 6 ^ {\frac {1} {3}})} =\\\frac {1} {(6 ^ {\frac {1} {3}}) * (6 ^ {\frac {1} {3}})} =\\\frac {1} {6 ^ {\frac {2} {3}}}$

ANswer:

$\frac {1} {6 ^ {\frac {2} {3}}}$
