Answer:
Option (2)
Step-by-step explanation:
Equations of the lines have bee given as,
y =
y =
Both the equations are in the slope intercept form. (y = mx + b)
They have same slopes but different y-intercepts.
Same slopes of the equations define the lines to be the parallel lines.
Therefore, Option (2) will be the correct option.
Answer:
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
Permutations of four letters from a set of 12 letters. So
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
