Answer:
4x-7y = -21
Step-by-step explanation:
1. Move 4/7x to the other side
-4/7x+y=-3
2. Multiply both sides by -7
4x-7y=-21
Answer:
x = 2.3202
Step-by-step explanation:
Given equation:
on taking log both sides, we get
now,
using the property of log function
log(aᵇ) = b × log(a)
therefore,
we get
(3x-5)log(10) = xlog(7)
now,
log(10) = 1
and
log(7) = 0.84509
thus,
( 3x - 5 ) × 1 = 0.84509x
or
3x - 0.84509x - 5 = 0
or
2.15491x = 5
or
x = 2.3202
The early withdrawal fee on this account is $6.25
Step-by-step explanation:
Suppose you buy a CD for $1000
- It earns 2.5% APR and is compounded quarterly
- The CD matures in 5 years
- Assume that if funds are withdrawn before the CD matures, the early withdrawal fee is 3 months' interest
We need to find the early withdrawal fee on this account
∵ The annual interest is 2.5%
- Change it to decimal
∵ 2.5% = 2.5 ÷ 100 = 0.025
∴ The annual interest rate is 0.025
∵ The interest is compounded quarterly
∴ The interest rate per quarter = 0.025 ÷ 4 = 0.00625
∵ The early withdrawal fee is 3 months' interest
∵ You buy the CD for $1000
∵ A quarter year = 3 months
∴ The early withdrawal fee = 1000 × 0.00625 = $6.25
The early withdrawal fee on this account is $6.25
