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>

John deposited $800 dollars in a bank that pays 5% interest per year. Find how many years it would take for his money to grow $9

gregori [183]

Answer:

It will take 3 years and 9 months or simply 3.75 years

Step-by-step explanation:

For his money to grow to $950, this means he had earned an interest of the value $950 - $800 = $150

Now, to calculate the number of years it took to earn this interest, we make use of the simple interest formula

mathematically,

I = PRT/100

since we are looking for T, we can rewrite the equation to be?;

100I = PRT

T = 100I/PR

where I is the interest which is $150

R is the rate charged on the deposit and that is 5% per annum

P is the amount deposited initially which is 800

while I is the interest which is $150

Now plugging these values;

T = (100 * 150)/(5 * 800)

T = 15000/4,000 = 3.75 years or simply 3 + (0.75 * 12) = 3 years 9 months

What is the solution to the system of equations?

Burka [1]

Answer:

(10, -20).

Step-by-step explanation:

y= -5x + 30

x = 10

Substitute x = 10 in the first equation:

y = -5*10 + 30

y = -50 + 30

y = -20.

So the solution is (10, -20).

Three boards are placed end to end to make a walkway. The first board is 4 feet 5 inches long, the second board is 6 feet 9 inch

Kazeer [188]

Answer:

15 feet and 1 inch long

Step-by-step explanation:

add up the feet: 4+6+3= 13 feet

add up the inches: 5+9+11 = 25 inches

25/12= 2 feet 1 inch

13 feet + 2 feet + 1 inch= 15 feet 1 inch
