Answer:
31/10
Step-by-step explanation:
We can find the slope given two points.
m = (y2-y1)/ (x2-x1)
= (-18-13)/(2 - 12)
= (-31)/(-10)
31/10

81, 27 and 9 are all powers of 3.
Let's write them in terms of 3.
81 = 3^4
Therefore we can write,
and since 27 = 3^3 we can write,
and 9 is 3^2.
So our equation looks like this,
Applying our exponent rule, division to subtraction, gives us,
And from this point, since the BASES are the same,
we can simply equate the exponents:
4(x-2)-3x = 2
and then solve for x.
