Hey there
The slopes of perpendicular lines are negative reciprocals. <span>Perpendicular lines have slopes that are </span>negative reciprocals<span> of each other.</span><span>

Answer:
Slope=3
Step-by-step explanation:
Using the points (0,3) and (1,3) we can use the slope formula.
m=rise = y2-y1
----- --------
run. x2-x1
or. m=3 = (3-0) = 3 = 3
- ------ -
1 (1-0) 1
1/2 + 2x = (3+4+12)x / 12
1/2 + 2x = 19x/12
1/2 = -5/2 x
x = -1/5
Step-by-step explanation:
Choosing 4 digits out of 10 = 10C4 = 210.
Arranging the 4 digits in 4 places = 4!
Total number of ways to arrange digits
= 210 * 4! = 5040.
Choosing 2 letters out of 26 = 26C2 = 325
Arranging the 2 letters in 2 places = 2!
Total number of ways to arrange letters
= 325 * 2! = 650.
Total number of possible license plates
= 5040 * 650 = 3,276,000.
4+|k+1|<15
-4 -4 15-4=11
|k+1|<11 |k+1|=k+1
k+1<11
-1 -1
k<10
