Your parents are buying a house for 187 500 they have a good credit rating are making a 20% down payment and expect to pay $1,575/month the interest rate for the mortgage is 4.65% what must their realized income be before each month and how much interest is paid by the end of the second month

For the answer to the question above, $187,500 is a cost of a house. 20%, or $37,500 is the down payment. The loan amount would be $187,500 - $37,500 = $150,000. If we assume the annual rate of the loan is 4.65% Then the monthly rate would be 4.65%/12 = 0.3875% If the loan is $150,000, the interest is 0.3875% The interest for the first month is $150,000 * 0.3875% = $581.25. You stated that their payment is $1,575. So the amount that pays off the loan is $1,575 - $581.25 = $993.75. At the end of the month, they owe $150,000 - $993.75 = $149,006.25 and for the second month, the amount of the payment that goes towards interest is $149,006.25 * 0.3875% = $577.40. and the amount that goes towards the loan is $997.60.

At the end of the second month, they owe $148,008.65. Regarding they realized income, we recommend a monthly loan payment not to exceed 28% of the monthly income.
So if a payment of $1,575 is 28% of Gross,
Then it must be
: $1,575 = 0.28*Gross. Gross = $5,625 monthly.
About $67,500 annually. About $33.75 an hour.

The x intercepts will be when the factors equal zero. The maximum and minimum is dependent on the leading coefficient.

Step-by-step explanation:

Factor this trinomial into two binomials, then set each factor equal to zero to solve for x, these will be the intercepts your teacher is asking for. You could also use quadratic formula to find them.

Then look at the leading coefficient. Is it positive or negative? Remember if positive the parabola goes up and negative the parabola goes down.
