What is the x-intercept of the line with this equation 1/3x+y= -15?<br><br> (_,0)
Sidana [21]

( - 45, 0)

to find the x-intercept let y = 0 in the equation

x = 0 → \frac{1}{3} x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

x-intercept = ( - 45, 0)

The functions f(x) and g(x) are shown.
erastova [34]

The function f(x) takes on the value 2 when x =  -7 and x = -3, and thus the corresponding points are (-7,2) and (-3,2).

The points where g(x) = 0 are called "roots" or "solutions," and is (3,0).

f(x) > g(x)  on the approx. interval (-9, -3/4).

A promissory note for $3600.00 dated May 15, 2012, requires an interest payment of $370.00 at maturity. If interest is at 9.6% c
vladimir1956 [14]

The due date of the promissory note is May 24th 2013.

Data;

  • Present Value (PV) = $3600
  • Interest = $370
  • Future Value (FV) = PV + I = $3600 + $370 = $3970

<h3>Due Date of the Note</h3>

To calculate the due date of the note, we can use the formula of future value of the note.

FV = PV (1 + \frac{r}{n})^d\\ 3970 = 3600 (1 + \frac{9.6}{12})^d\\3970 = 3600(1+0.008)^d\\\frac{3970}{3600} =(1.008)^n

Let's take the natural log of both sides

(1.008)^n = (\frac{3970}{3600})\\ n\ln(1.008) = \ln(\frac{397}{360})\\ n = 12.28

This is approximately 12 months and 9 days.

The due date of the promissory note is May 24th 2013.
