Answer:
120 ways
Step-by-step explanation:
Since no girl wil sit either first or last
Hence, in all irrespective whether boy or girl = (6 - 1)! = 5! = 5 X 4 X 3 X 2 = 120
∴ Number of arrangements = 120 ways
11. x is greater than or equal to -1
12. x is less than -1
Answer:15 or 30
First solve for y
3x-y-2=1
subtract 3x from each side
-y-2=-3x+1
add 2 to both sides
-y=-3x+3
divide each side by -1
y=3x-3
To graph you could make a table:
x y
0 -3
graph that.... point and use rise over run for slope 3/1 and graph.
y=-x
J(-4,3)
K(3,-4)
L(1,1)
