The y-intercept is being changed. In the equations given we are using the formula (y=mx +b), b means the y intercept. In this we are changing the y intercept from 2 to -1. There is nothing else being changed.

Answer:
11,8,5
Step-by-step explanation:
an=11-3(n-1)
Let n=1
a1 = 11 - 3(1-1)
= 11 -0
=11
Let n=2
a2 = 11-3(2-1)
= 11 -3(1)
= 8
Let n=3
a3 = 11-3(3-1)
= 11 -3(2)
= 11 -6
=5
The value of the coin times the number of coins all added up equals the total value of the piggy bank
so
0.05n + 0.10d = 5.60
then they have given us "number of nickels is 8 less than 3 times the dimes"
this translates to
n = 3d - 8
we plug this into our first equation and we get
0.05(3d - 8) + 0.10d = 5.60
now we solve for d
first we can distribute the 0.05
0.15d - 0.40 + 0.10d = 5.60
then we can add the 0.15d and 0.10d together
and get
0.25d - 0.40 = 5.60
then we can add 0.40 to both sides
0.25d = 6.00
then divide both sides by 0.25
d = 6.00 / 0.25 = 24
so we have 24 dimes
then to find nickels, we plug in 24 for d into
n = 3d - 8
and get
n = 3(24) - 8
n = 72 - 8
n = 64
therefore we have
64 nickels
and
24 dimes
Answer:
Amount = Rs. 30250 when Rate = 10%
<em>Amount = Rs. 31360 when Rate = 12%</em>
Step-by-step explanation:
Given
Number of times (n) = Annually
Required
Determine the Amount for both Rates
Amount (A) is calculated by:
When Rate = 10%, we have:
Substitute 25,000 for P; 2 for t; 1 for n and 10% for r
Convert 10% to decimal
Hence;
<em>Amount = Rs. 30250 when Rate = 10%</em>
When Rate = 12%, we have:
Substitute 25,000 for P; 2 for t; 1 for n and 10% for r
Convert 12% to decimal
Hence;
<em>Amount = Rs. 31360 when Rate = 12%</em>
