Find the slope of the given points (2,5) and (8,-3) and write the equation​
max2010maxim [7]

Answer:

Slope = \frac{-4}{3}

4x + 3y = 23

Step-by-step explanation:

slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-3-5}{8-2} =\frac{-8}{6} =\frac{-4}{3}

The equation:

\frac{y-y_{1} }{x-x_{1} }=m   m is the slope

y-y_{1}=m(x-x_{1} )

y - 5 = -4/3 (x - 2) Multiply both sides by 3

3y -15 = -4 (x - 2)  

3y - 15 = -4x + 8

3y + 4x = 8 + 15

3y + 4x = 23

4x + 3y = 23

The circumference of circle p is 800 mm, the circumference of circle q is 200 cm, and the circumference of circle r is 4 m. What
shepuryov [24]

Let us use the following conversions:

1 cm = 10 mm

1 meter = 100 cm = 1000 mm

Given:

p = 800 mm

q = 200 cm = 2000 mm

r= 4 m = 4000

X = sum of the distance around each circle

X = p+q+r

X = 800+2000+4000

<span>X = 6800 mm or 680 cm or 6.80 m</span>

Captain Emily has a ship, the H.M.S Crimson Lynx. The ship is four furlongs from the dread pirate Ashley and her merciless band
aalyn [17]

Answer:

1/2

Step-by-step explanation:

Since the Captain shoots first, the probability of a hit on the pirate ship is 1/2. In the event of a hit, the pirate will always miss (p(miss|hit)=1), so ...

... p(hit, miss) = 1/2
