Answer:
Question (i):
Reduce = 15% of Rs 40 = 0.15 x 40 = Rs 6
Price after reduced = Rs 40 - Rs 6 = Rs 36
Answer: Rs 36
-
Question (ii):
Reduce = 15% x 20.40 = 0.15 x 20.40 = Rs 3.60
Price after reduced = Rs 20.40 - Rs 3.60 = Rs 17.34
Answer: Rs 17.34

4) the distance between the x-values is 3 and the distance between the y-values is 4
3² + 4² = d²
9 + 16 = d²
25 = d²
√25 = d
5 = d
Answer: C
6)
d = 
d = 
d = 
d = 
d = 
d = 
d = 6.1
Answer: A
Answer:
The factor of 12x^2 + 16 is 4x (3x+4)
The companies being considered are:
The company that is concerned with corded telephones
The company that is concerned with cellphones
Let x represent the number of years since 2002 and y represent the total number of accounts
From the information given,
Considering the first company,
Initial number of accounts = 946 x 10^6
The number of accounts fell by approximately 28 million per year. This means that in x years, the number of accounts that would have been lost is
28 x 10^6 * x
= - 28x x 10^6
It is negative because it is reducing
The slope intercept form of a linear equation is expressed as
y = mx + c
where
m = rate of change
c = y intercept of value of y when x = 0
By comparing with the given scenario,
