Answer: -101
Step-by-step explanation: f(n) = 19-6*n
f(20) = 19 - 6*20
f(20) = -101
If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.
For example. - "11055"
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)
In short, This number would be divisible.
Hope this helps!
Answer:
-2
Step-by-step explanation:
you have to rearange in the form of
y=mx+b, where m is the slope
y -6= -2( x-8)
y = 6 -2x + 16
y= -2x +22
slope is -2
Answer:
- 10 and 2
Step-by-step explanation:
-10 x 2 = -20
-10 + 2 = -8
The answer would be c = 5.
2/5 = 2/c
2/5c = 2
2c/5 = 2
2c = 2 * 5
2c = 10
c = 10/2
c = 5.
Hope this helps and happy studying :).
