Answer:

THERE'S two  SOLUTION

Step-by-step explanation:

-4(x+5)=-4x-20

1) multiply -4 by x which is -4x then multiply -4 by 5 which gives -20

-4x-20=-4x-20

2) send 20 over on the other side and turn it to a positive 20

-4x=-4x+20-21

3) rewrite the equation -4x=-4x because a positive plus a negative is a negative which means you're subtracting

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 6 is added to the product of 7 and a number 7. The expression will be written as,

Determine the amount needed such that when it comes time for retirement, an individual can make semiannual withdrawals in the am
Alex787 [66]

Answer:

--------------------------------------------------------------------------------------------------------------

$535,528.03

Since the semiannual withdrawals will be made for 35 years, the annuity will have two payments per year.

You may use a financial calculator to calculate the balance that will match the present value of your annuity distributions when you retire. The following are the inputs:

N = 35*2 = 70 semi-annual withdrawals total time

I/Y = 4.5 percent /2 = 2.25 percent semi-annual interest rate

FV = 0 (future value) (use 0 in annuity if not given)

PMT = 15,265; semi-annual payment

Enter the functions to find PV: CPT PV = 535,528.026

As a result, the person will need $535,528.03 in cash.
