Answer: yes, it is
Step-by-step explanation:
A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.
n = k(k+1)(k-1)
If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.
Now, if k-1 is a multiple of 3, it can be even or odd.
if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6
if k-1 is odd, then k and k+1 is even, hence, divisible by 2.
As n = k(k+1)(k-1), n is also divisible by 6.
Answer:
73
Step-by-step explanation:
7x7 is 49+3=52(4x4=16+5=21 then you would do 52+21=73 and 3+2 is 5
7x7+3=52
4x4=16
3+2=5
16+5=21
52+21=73
73 is answer
Answer:
<em>y = -3x + 2</em>
Step-by-step explanation:
From the graph, you see the line intersects the y-axis at y = 2, so the y-intercept is b = 2.
Now we need the slope. We need to find the number of vertical and horizontal units to go from one point to the other. Starting at point (-1, 5), go down 6 units and then go right 2 units. The change in y is -6. The change in x is 2. slope = m = (change in y)/(change in x) = -6/2 = -3.
m = -3; b = 2
y = mx + b
y = -3x + 2
