Let c be the distance between Carlisle and Wellesley, let b be the distance between Carlisle and Stonebridge, and let a be the distance between Wellesley and Stonebridge.
· If you did a circuit, traveling from Carlisle to Wellesley to Stonebridge and back to Carlisle, you would travel 73 miles.
· The distance from Stonebridge to Carlisle is 12 miles farther than the distance from Wellesley to Carlisle..
· If you drove from Stonebridge to Carlisle and back to Stonebridge, and then continued to Wellesley then back to Stonebridge, you would travel 102 miles.

Assume that a family is purchasing a typical house by making a $30,000 down payment and then financing a $250,000 mortgage at an annual interest rate of 4.25% (a typical rate for a 30-year loan). The size of their monthly payment will depend on the term of the mortgage.
The formula or the Excel function “pmt” can be used to compute these monthly mortgage payments. If using Excel the 3 arguments of function “pmt” are:
Rate (the monthly interest rate): 0.0425/12
Nper (the total number of monthly payments) and
Pv (the mortgage amount)

Find the monthly payments if the $250,000 was financed over 15 years.
Find the monthly payments if the $250,000 was financed over 30 years.
Multiply your answer to part (a) by the number of payments to find how much the family would need to pay in total over the life of the 15-year loan. Subtract the principal amount from this to give the amount of interest paid over the life of the loan.
Multiply your answer to part (b) by the number of payments to find how much the family would need to pay in total over the life of the 30-year loan. Subtract the principal amount from this to give the amount of interest paid over the life of the loan.
A standard rule for lenders is that a family’s house payment should not exceed 28% of their monthly income. For a family making $5500 per month, this would equate to $1540 per month. Assuming monthly costs of $250 for property tax and homeowner’s insurance, this would allow for a $1290 monthly mortgage payment.
The formula or the Excel function “pv” can be used to compute the mortgage a family could afford. If using Excel the 3 arguments of function “pv” are:
Rate (the monthly interest rate): 0.0425/12
Nper (the total number of monthly payments) and
Pmt (the monthly mortgage amount)

Assuming that a family wants to make a $1290 monthly payment, give the mortgage that a family could afford at an annual interest rate 4.25% for a 15-year mortgage.

I have two points $(0, 0)$ and $(93, 3)$
I'm trying to work out whether a point is on or below the line segment defined by those two point.
Currently I'm using $A x + B y + C = 0$ to see if a point is on or below this line segment and this works correctly except for when the point is of the form $(0, y)$ or $(x, 0)$
What am I doing wrong? Do I need to use a different form of the linear equation?

I am trying to solve a system of linear equations that is underdetermined. Meaning the number of unknown is more than the equations. The system is of the form $A x = 0$ . I have seen methods of solving this type of problem when the right hand side is nonzero. Namely, $A x = b ⟹ x = (A^{T} A)^{-} A^{T} b$ . But this method is inapplicable when $b = 0$ . Any suggestions?

Suppose $a_{k} = \frac{1}{2} p (a_{k + 1} + 1) + \frac{1}{2} p (a_{k - 1} + 1) + (1 - p) (a_{k} + 1)$ for $0 < k < n$ and $a_{0} = a_{n} = 0$ and $0 < p < 1$ . How do we find a closed form of $a_{k}$ ? For $p = 1$ , I know the solution is $a_{k} = k (n - k)$ . But I have no idea about this case. It is a system of linear equations, so I think it will a unique solution. In fact, the problem comes from random walk on ${0, 1, 2, . . ., n}$ with absorbing states $0, n$ . And $a_{k}$ is the expectation of number of steps reaching absorbing states when starting at $k$ .
$a_{k} = \frac{1}{2} p (a_{k + 1} + 1) + \frac{1}{2} p (a_{k - 1} + 1) + (1 - p) (a_{k} + 1) \Leftrightarrow p a_{k} = 1 + \frac{1}{2} p a_{k - 1} + \frac{1}{2} p a_{k + 1}$ . Thus if we let $b_{k} = p a_{k},$ , then it is equivalent to $b_{k} = 1 + \frac{1}{2} b_{k - 1} + \frac{1}{2} b_{k + 1}$ , which has solution as above. But how to solve this one about $b_{k}$ ?

Students dealing with post-secondary Algebra will know that linear equation standard form examples are quite hard to find, let alone obtain solutions to questions related to algebraic problems. Luckily, you will find suitable answers to your linear equation standard form tasks by turning to help based on provided solutions. Even though one may use several calculators online, the college professors will require a verbal or written explanation, which is where provided forms of linear equations answers always help to avoid trouble and see the reasoning.
