Answer:

○ B. \displaystyle \frac{2r^4}{s^3}

Step-by-step explanation:

First off, whenever you divide similar bases, you keep the base and subtract the exponents, so you will have this:

\displaystyle {2r^4s^{-3}}

Now this IS the correct, but although we do not see it here, we have to deal with that negative exponent, and according to the Negative Exponential Rule [part I], you bring this part of the numerator to the denominator WHILE ALTERING THE SIGN FROM NEGATIVE TO POSITIVE, so you will have this final answer:

\displaystyle \frac{1}{b^n} = b^{-n} \\ \\ \frac{2r^4}{s^3}

I am joyous to assist you anytime.

The line through (-2, 3) with slope 2/3 in point slope form​
Debora [2.8K]

Answer:

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

Step-by-step explanation:

slope = 2/3

point-slope form --> y - y1 = m(x - x1)

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

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

point slope form of the line is y - 3 = 2/3(x + 2)
