\\ \sf\longmapsto \dfrac{8^{2x+1}}{64}=8^3

\\ \sf\longmapsto \dfrac{8^{2x+1}}{8^2}=8^3

  • a^m÷a^n=a^{m-n}

\\ \sf\longmapsto 8^{2x+1-2}=8^3

\\ \sf\longmapsto 8^{2x-1}=8^3

\\ \sf\longmapsto 2x-1=3

\\ \sf\longmapsto 2x=3+1

\\ \sf\longmapsto 2x=4

\\ \sf\longmapsto x=\dfrac{4}{2}

\\ \sf\longmapsto x=2

The space shuttle releases a space telescope into orbit
sergey [27]

Answer: 68 m/s^{2}

Step-by-step explanation:

The acceleration a of the satellite can be calculated by the following equation:

V_{f}=V_{o}+at

Where:

V_{f}=1700 m/s is the final speed of the satellite

V_{o}=0 is the initial speed of the satellite (it was "stationary" before the release)

t=25 s is the time

Isolating a:

a=\frac{V_{f}}{t}

a=\frac{1700 m/s}{25 s}

Finally:

a=68 m/s^{2}

-6-2b=-8. What's the answer
Ksivusya [100]

Answer: B = 1

Step-by-step explanation: The first step is to add 6 to both sides of the equation to get -2b = -2

You then divide both sides by negative 2 so you can get a positive

dividing both sides by negative 2 will leave you with 1b = 1

so

b = 1
