disa [49]

Answer:

Below.

Step-by-step explanation:

As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.

W then solve this equation for x then substitute this value of x  in the first equation ( y = 3x + 1) to find the value of y.

Simplify the expression.
denis23 [38]

Answer:

option d

Step-by-step explanation:

\sf \boxed{a^m*a^n = a^{m+n}\\\\}

\sf \left(\frac{m^{-1}m^{5}}{m^{-2}} \right)^{-3} =\left(\dfrac{m^{-1+5}}{m^{-2}}\right)^{-3}

                 \sf = \left(\dfrac{m^4}{m^{-2}}\right)^{-3}\\\\

\boxed{\dfrac{a^{m}}{a^{n}}=a^{m+n}}

                    \sf = \left(m^{4-[-2]}\right)^{-3}\\\\      =\left(m^{4+2}\right)^{-3}\\\\       = \left(m^6\right)^{-3}\\\\

\boxed{(a^{m})^n=a^{m*n}}

                    \sf= m^{6*(-3)}\\\\    = m^{-18}

\boxed{a^{-m}=\dfrac{1}{a^m}}

                    \sf=\dfrac{1}{m^{18}}
