It should be noted that:
1 point = 1% = 0.01
Therefore,
Cost of points = Number of points*0.01*Mortgage
Substituting;
Cost of discount points = 5*0.01*231,000 = $11,550
Cost of originating points = 4*0.01*231,000 = $9,240
x^2 + 10x = - 5
To complete the square, we need to add a constant on the
left side that makes the expression on the right a perfect square trinomial. We
need to add the same value on the right side to keep the equation equal. So,
x^2 + 10x + a = -5 + a
where a is the square of one-half the coefficient of x, therefore:
a = (10 / 2)^2 = 25
x^2 + 10x + 25 = -5 + 25
(x + 5)^2 = 20
Taking the square root of both sides:
x + 5 = ± 4.47
x = -5 ± 4.47

Answer:
y = 40.96
Step-by-step explanation:
Given
4 = ( multiply both sides by 10.24 to clear the fraction )
4 × 10.24 = y , that is
y = 40.96
