How to convert nonlinear equation to linear equation?
9966 [12]
Let's take the non-linear equation:
{x}^{2}  =  \sqrt{3} y
First Make The Equation To Be In Terms of Y

*Divide Both sides by
\sqrt{3}
\frac{ {x}^{2} }{ \sqrt{3} }  =  \frac{ \sqrt{3} y}{ \sqrt{3} }
*Simplify
\frac{ {x}^{2} }{ \sqrt{3} }  = y
You shouldn't keep a radical in the denominator, however we leave it for the purpose of the reciprocal.

*Take The Reciprocal Of Both Sides
\frac{ \sqrt{3} }{ {x}^{2} } =  \frac{1}{y}
A Linear Equation Takes The Format:
y = mx + b
So,
\frac{1}{y}  = y
b = 0
m(slope) =  \frac{ \sqrt{3} }{x}
x =  \frac{1}{x}
Resulting in :
\frac{1}{y}  =  \frac{ \sqrt{3} }{x}  (\frac{1}{x} ) + 0

Alona [7]

Answer:

1 Chair= $1.25     1 table= $8.25

Step-by-step explanation:

5c+3t=31

2c+6t= 52

-2(5c+3t=31)

-10c-6t=-62

+

2c+6t=52

= -8c=-10

/-8      /-8

c= 1.25 or 1 1/4

2c+6t=52

2(1.25)+6t=52

2.5+6t=52

-2.5        -2.5

6t= 49.5

/6      /6

t= 8 1/4
