Answer: $78150 would be in the account after 8 years
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $65,000
r = 2.3% = 2.3/100 = 0.023
n = 12 because it was compounded 12 times in a year.
t = 8 years
Therefore,.
A = 65000(1 + 0.023/12)^12 × 18
A = 65000(1 + 0.00192)^96
A = 65000(1.00192)^96
A = $78150
≥The solution of an inequality is an interval, i.e. a range.
To prove that the interval found as solution, you must consider several cases.
1) In the case that the ineguailty is ≥ or ≤, first use the limits of the interval to prove they are valid solutions. This is, replace the limit values, one at a time, and verifiy the inequality.
2) If the sign is ≥ or > use a value to the right of the limit value to show that the values to the right are solution, and use a value to the left to show that they are not solution.
3) If the sign is ≤ or <, use a value to the left of the limit value to show that it is a solution and a value to the right of the limit value to show that it is not a solution.

Answer:
Step-by-step explanation:
the sum of 5x+20= 5(x+4)
and the opposite of 20 is negtive 20
Answer:
4x + 2y = 2
Step-by-step explanation:
8x + 4y = 2 ( divide each term by 2 )
4x + 2y = 1 → (1)
we require a situation where the left side cannot possibly equal the right side.
using 4x + 2y = 2 → (2)
subtract (1) from (2) term by term
(4x - 4x) + (2y - 2y) = 2 - 1 , that is
0 + 0 = 1
0 = 1 ← not possible
thus the system has no solution
