Alex took out a 7/1 variable-rate mortgage for $140,000. the interest rate for
the first period was fixed at 5.25%, and the loan was amortized over 30 years.
at the end of the initial loan period, the interest rate was 6.75%, plus a 1.5%
margin. what will the unpaid balance on his mortgage be after his initial
period expires?
a. $123,740.97
b. $126,805.34
c. $123,739.09
d. $122,773.09

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
