Slope = (y2-y1)/(x2-x1) = (8-2)/(3-1) = 6/2 = 3. So the answer is c.
To factor you have to do this:
s^2 + 9s = -20
+ 20 +20
s^2 + 9s + 20 = 0
now you need to numbers that multiplied give you 20
and then those same 2 numbers have to add to 9
5 x 4 = 20
5+ 4 = 9
(x + 4) (x+ 5)
that means that x= -4, and -5
The value of m from the equation is -1/5
<h3>Solving equations and expression</h3>
Given the equation below expressed as;
3(5m + 2) = 3
Expand
3(5m) + 3(2) = 3
15m + 6 = 3
Subtract 6 from both sides
15m + 6 - 6 = 3 - 6
15m = -3
Divide both sides by 15
15m/15 = -3/15
m = -1/5
Hence the value of m from the equation is -1/5

Answer:
12 OR 1/12 (Check how you write your equations! Just look below for the one that it actually is lol)
Step-by-step explanation:
6 = (1/2)n
6/(1/2) = n
12 = n
OR
6 = 1/(2n)
6(2n) = 1
12n = 1
n = 1/12
