Is x^2 + 1/x = 4 a quadratic equations

Liono4ka [1.6K]

Answer:

$\large\boxed{\pink{ \leadsto The \ given \ equation \ is \ not \ a \ Quadratic \ equation . }}$

Step-by-step explanation:

Given equation to us is ,

$\green{\implies x^2+\dfrac{1}{x}=4 }$

So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,

$\implies x^2 +\dfrac{1}{x}=4$

Taking x as LCM ,

$\implies \dfrac{x^2.x + 1 }{x}= 4$

Transposing x to RHS .

$\implies x^3 + 1 = 4x$

Putting all terms in LHS

$\boxed{\bf \implies x^3 - 4x - 1 = 0 }$

Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

<h3>Hence the given equation is not a quadratic equation .</h3>

A bakery uses 10 3/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake?

natita [175]

Answer:

$42\frac{2}{5}}\frac{ounces}{cake}$

Step-by-step explanation:

we know that

To calculate the unit rate divide the total ounces by 1/4 of a cake

but first convert mixed number to an improper fraction

$10\frac{3}{5}\ ounces=\frac{10*5+3}{5}=\frac{53}{5}\ ounces$

$\frac{(53/5)}{(1/4)}=\frac{53*4}{5}=\frac{212}{5}\frac{ounces}{cake}$

Convert to mixed number

$\frac{212}{5}\frac{ounces}{cake}=\frac{210}{5}+\frac{2}{5}=42\frac{2}{5}}\frac{ounces}{cake}$
