It looks like you're trying to solve
3x₁ + 7x₂ + s₁ = 49
x₁ +4x₂ +s₂ = 31
Fill in the given values for x₁ and s₁ and your system reduces to
7x₂ = 49
4x₂ +s₂ = 31
The first of these equations tells you x₂ = 49/7 = 7, so the second equation becomes
28 +s₂ = 31
and it is immediately obvious that s₂ = 3
Your solution is (x₁, x₂, s₁, s₂) = (0, 7, 0, 3).
This is really weird.
-- NONE of the situations matches the equation at the top.
-- And the equation at the top isn't even really any big deal . . .
it's <em>always</em> true, no matter what ' t ' is . If you remove all of
the parentheses and simplify it, it says that 6 = 6. Well duh !
I think the answer is 0.399
the "9" is repeated.
Answer:its the second answer
Step-by-step explanation:
Answer:
The remaining amount is $360.34
Step-by-step explanation:
we will be using the present value annuity in this problem to solve for the present value of the ninth year of all remaining payments that means for the remaining 4 years including the ninth year, The present value formula :
the present value annuity calculates the present value of future payments that will be made through a period in a given time or given number of periods, so here we are given the following information:
$100 is a periodic payment so it will be represented by C.
1% is the interest rate (i) for the 12 years .
n is the period or the number of payments made so in this case we will use n=12 payments to calculate how much in present value is the amount by the end of the 12th payment year then we will subtract the present value for n=8 to calculate the present value at the end of the 8th year then the difference will be the present value at the beginning of the ninth year.
we will substitute the values on the above mentioned formula :
Present value = 100[(1-(1+1%)^-12)/1%] - 100[(1-(1+1%)^-8)/1%] compute
present value = $360.34 this will be the present value at the beginning of the 9nth year.
