Answer:
1.6
2. Honestly, I think it is, because it repeats at regular intervals. The period is -2.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
There are 9 letters, which contains 2Qs, 3Ls and 4Bs.
If the 9 letters are distinct, the number of permutations they have will be 9!.
! is the factorial sign.
9! = 9*8*7*6*5*4*3*2*1
HOWEVER, we have some identical elements, so we need to get rid of the permutations of the same letters.
Thus we have:

The answer is D
Good morning
______
Answer:
2/3 < 3/4
___________________
Step-by-step explanation:
2/3 = (2*4)/(3*4)=8/12
3/4 = (3*3)/(4*3)=9/12
Since 9/12>8/12 then 3/4>2/3

Answer:
D)
Step-by-step explanation:
∠1 + ∠2 = 180 {linear pair}
x - 29 + x + 61 = 180 {add the like terms}
2x + 32 = 180 {subtract 32 from both sides}
2x + 32 - 32 = 180 - 32
2x = 148
x = 148/2
x = 74
∠1 = x - 29 = 74 - 29 = 45
∠2 = x + 61 = 74 + 61 = 135
The slope of the line of the equation given is -2 (by solving for y, you get y = -2x+4).
So, in order to be perpendicular, you must take the negative reciprocal.
The slope would be -1/2.
