consider the equation is Y equals 1/square root of x and y=x-2. approximate solution of the system equations
emmasim [6.3K]

Answer:

x=1 and x=4

Step-by-step explanation:

We have the following system of equations:

y=\sqrt{x} and y=x-2

To solve the problem, we need to equal the two equations:

x-2=\sqrt{x} ⇒ (x-2)^{2} =x ⇒ x^{2} -4x + 4 = x  

⇒ x^{2} -5x + 4 = 0  

So you need to find two numbers that added equal to 5 and multiplied equal to 4. These two numbers are x=-1 and x=-4.

Then, the factorized form of the polynomial is: (x-1)(x-4).

The, the solution to the system of equations is: x=1 and x=4.

Jared is redoing his bathroom floor with tiles measuring 6 in. by 14 in. The floor has an area of 8,900 in. What is the least nu
Bond [772]
Firstly we need to find an area of a single tile:

6 * 14 = 84 square inches

Now we just need to find out how many tiles of 84 square inches will fit in an area of 8900 square inches:

8900 ÷ 84 = 105,952380952381

Assuming we can't cut a tile into pieces, we may round the result to 106.

Answer: The least number of tiles Jared will need is <u>106</u>.
