Please solve this equations y=6x²-5,y=17x-6/x

Amiraneli [1.4K]

Answer:

$x=3, y = 49\\x=0.5, y = -3.5\\x=-0.67, y = -2.31$

Step-by-step explanation:

$y=6x^2-5\\y=17x-\frac{6}{x}$

Let's substitute the first equation into the second one.

$6x^2-5=17x-\frac{6}{x}$

$6x^3-17x^2-5x+6=0$ - Multiply by $x$ and bring all the terms to one side.

I'll use my graphical calculator to solve this but you could factor:

$x=3\\x=0.5\\x=-0.67$ (All rounded to 2 decimal places)

Now we can substitute these $x$ values into an equation for $y$ .

$y=6x^2 - 5$

$x=3, y = 49\\x=0.5, y = -3.5\\x=-0.67, y = -2.31$

Olegator [25]

Answer:

17.3 years

Step-by-step explanation:

For some annual interest rate r and time in years t, the initial account value is multiplied by e^(rt).

You want the multiplier e^(.04t) to have a value of 2:

2 = e^(.04t)

ln(2) = 0.04t . . . . . take natural logs

t = ln(2)/0.04 = 17.329 . . . . . divide by the coefficient of t

It will take about 17.3 years for the investment to double.
