Answer:
k-n+1
Step-by-step explanation:
How many numbers are written from n to k
Lets look at a smaller example with real number
Lets go from 3 to 8
3 4 5 6 7 8
There are 6 numbers
We take 8 -3 = 5, but we include the number 3 so we add it back in +1
5+1 =6
Lets look at a larger example
2 to 11
2,3,4,5,6,7,8,9,10,11
There are 10 numbers
11-2 =9 but we have to add back in the first number
9+1 =10
Now we are going from n to k
k-n = k-n, but we have to add back in the first number
k-n+1
Answer: 7
Step-by-step explanation:
denotes the intersection of A and C, or in other words, how many elements are shared between them.
The number of elements is 2 + 5 = 7
Answer:
y = 4x - 1
Step-by-step explanation:
To write the equation of a line using the slope and a point, use the point slope form 
.
Substitute m = 4 and (3,11).
y - 11 = 4 ( x- 3)
y - 11 = 4x - 12
y = 4x - 1
Step-by-step explanation:
the 1st shop=196-(17.5/100×196)
=196-34.3
=161.7+196
=357.7
the 2nd shop=196-(22.5/100×196)
=196-44.1
=151.9+196
=347.9
so the difference between two shop is
357.7-347.9=9.8
