7 0

Answer:

y = 4/7x + 13/7

Step-by-step explanation:

m = 3+1/2+5 = 4/7

i used the coords (-5, -1)

y + 1 = 4/7 (x+5)

y + 1 = 4/7x + 20/7

y = 4/7x + 20/7 - 1

y = 4/7x + 13/7

How many extraneous solutions does the equation below have? StartFraction 9 Over n squared 1 EndFraction = StartFraction n 3 Ove
BigorU [14]

The equation has one extraneous solution which is n ≈ 2.38450287.

Given that,

The equation;

\dfrac{9}{n^2+1} =\dfrac{n+3}{4}

We have to find,

How many extraneous solutions does the equation?

According to the question,

An extraneous solution is a solution value of the variable in the equations, that is found by solving the given equation algebraically but it is not a solution of the given equation.

To solve the equation cross multiplication process is applied following all the steps given below.

\rm \dfrac{9}{n^2+1} =\dfrac{n+3}{4}\\\\9 (4) = (n+3) (n^2+1)\\\\36 = n(n^2+1) + 3 (n^2+1)\\\\36 = n^3+ n + 3n^2+3\\\\n^3+ n + 3n^2+3 - 36=0\\\\n^3+ 3n^2+n -33=0\\

The roots (zeros) are the  x  values where the graph intersects the x-axis. To find the roots (zeros), replace  y

with  0  and solve for  x. The graph of the equation is attached.

n  ≈  2.38450287

Hence, The equation has one extraneous solution which is n  ≈  2.38450287

tatyana61 [14]
<span>Interest=principle x rate x time (in years)
so putting values so
Interest=7500 (.042)(2)
 so
 Interest=630 7500+630=8130
 Interest=500 (.071)(4)
Interest=142 500+142=64
hope it helps</span>
