Veronica has two offers for a $65,000 student loan. The first loan has a 6.3% interest rate for 15 years, and the second loan ha
steposvetlana [31]

The second option has a lower amount of interest paid.

In order to determine the loan option that minimizes loan payment, the future value of both loan options has to be determined.

FV = P (1 + r)^nm

FV = Future value  

P = Present value  

R = interest rate  

m = number of compounding

N = number of years  

<em><u>First loan option </u></em>

65000( 1 + 0.063/12)^300 = 312,707.21

<em><u>Second loan option </u></em>

65000( 1 + 0.048/12)^240 = 169,435.51

Is the function linear, exponential or neither ? Help me please
Svetradugi [14.3K]

Hello! :)

\large\boxed{\text{Linear.}}

The function pictured is a straight line, so it has a constant slope for all x values.

A function that has the same slope on its domain and when graphed is a straight line is a linear function.

Please solve this proportion with steps (I'm stuck)<br> (9x+6)/18= (20x+4)/3x
guapka [62]
\frac{9x+6}{18}=\frac{20x+4}{3x}

Cross multiply. Distribute...
3x(9x+6)=18(20x+4)\\27x^2+18x=360x+72\\27x^2-342x-72=0\\3x^2-38x-8=0

OH GOD IT'S A QUADRATIC
<em>(our equation is in ax² + bx + c = 0 form. a=3. b= -38. c= -8.
</em><em>plug these values into the quadratic formula and simplify.)</em>
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-(-38)\pm\sqrt{(-38)^2-4(3)(-8)}}{2(3)}=\frac{38\pm\sqrt{1444+96}}6\\\\\sqrt{1444+96}=\sqrt{1540}=\sqrt{4\times345}=2\sqrt{345}\\\\\frac{38\pm2\sqrt{345}}6=\boxed{x=\frac{19\pm\sqrt{345}}3}

Approximate values for x: -0.20714 or 12.874
