Answer:
C
Step-by-step explanation:
For the various values of X the values of Y are given as follows
X=-1; Y=3
X=0; Y=2
X=1; Y=3
X=2; Y=6
X=3; Y=11
Step-by-step explanation:
Step 1:
Let us consider the given expression as
Step 2:
Let us discuss the value of Y for the various values of X
If X = -1, Y = (-1)² + 2 = 3
If X = 0, Y = (0)² + 2 = 2
If X = 1, Y = (1)² + 2 = 3
If X = 2, Y = (2)² + 2 = 6
If X = 3, Y = (3)² + 2 = 11
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
Answer: Slope of the line formed by the data is -3.
m=-3 for y=mx+b.
Step-by-step explanation: The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line. I'll pick 2 points: (-4,17) and (9,-22). Any two points will work, if it is a straight line. For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y. x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.
The rise(y) over the run(x) for these points is thus (-39/13) = -3
The slope is -3
Just read the manual. I thought this was a question on an assignment or something.
