3y= 5x-2
so the slope is 5/3
The formula is a permutation in which n represents the sample points in the set, while r represents the number of sample points in each permutation.
-3•-4=12, and -3+-4=-7.
this will turn into
(x-3)(x-4)
set them up to equal zero
x-3=0, x-4=0
solve
x=3, x=4
(a)
3x+50 = 6x - 10
6x -3x = 50+10
3x = 60
x = 20
answer
x = 20
