1 answer:
Answer:
£1045.57
Step-by-step explanation:
Using compound interest formula then
Where A= the future value of the investment/loan, including interest
P = the principal investment amount
r = the annual interest rate
n = the number of times that interest is compounded per unit t
Hence her amount t the end of 5 yrs is $1045.57

Again, In this question too you need to substitute the given variable values into the original expressions. Here, "x" is given as a value of "12" and the variable of "y" is given as as value of "2". A single variable of "x" in the numerator is given in the expression. On the denominator the variable of "y" with a value of "2" is multiplied by a numbered value of "3". So, now showing this by the help of LaTeX.

Answer:
No solution
Step-by-step explanation:
Given equation is,
if x ≠ ±1
[Squaring on both the sides of the equation]
4 = (1 - x)(4 + x)
4 = 4 - 4x + x - x²
0 = -3x - x²
x² + 3x = 0
x(x + 3) = 0
x = 0, -3
But both the solutions x = 0 and x = -3 are extraneous solutions, given equation has no solution.
