Answer:

r = -17

Step-by-step explanation:

Slope = -5

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\frac{3 - r}{-8-[-4]}=-5\\\\\frac{3-r}{-8+4}=-5\\\\\frac{3-r}{-4}=-5\\

3-r = (-5)*(-4)

3 - r = 20

   -r = 20 - 3

  -r = 17

   r = -17

Jet001 [13]

Answer:

1728

Step-by-step explanation:

You could write it like this

5.4 * 10^5 * 3.2 * 10^-3  

You could do this by multiplying the numbers first

5.4 * 3.2 = 17.28

Now work with the powers of 10

10^5 * 10^-3 = 10^(5 - 3) = 10^2

10^2 = 100

So the answer is 17.28 * 100 = 1728
