Artyom0805 [142]3 years ago
5 0

Answer:

x = - 4

Step-by-step explanation:

Given

5x - 11 = 7x - 3 ( subtract 7x from both sides )

- 2x - 11 = - 3 (  add 11 to both sides )

- 2x = 8 ( divide both sides by - 2 )

x = - 4

Multiply and simplify if possible.<br> sqrt 5x(sqrt x-5 sqrt 5)
RSB [31]
Making the assumption that your problem looks like this,
\sqrt{5x}(\sqrt{x}-5\sqrt{5})

we use the distributive property to multiply:
\sqrt{5x}\times \sqrt{x}-\sqrt{5x}\times5\sqrt{5}&#10;\\&#10;\\ \sqrt{5x^2} - 5\sqrt{25x}&#10;\\&#10;\\ x\sqrt{5}-25\sqrt{x}

What are the domain and range of this function?
Arlecino [84]

Answer:

Correct answer:  The third answer is correct

Step-by-step explanation:

The domain of each function is defined by observing the behavior of the function from left to right by following the growth of numbers on the x axis of real numbers.

In the same way, the range of each function is defined by observing the behavior of the function from the bottom y axis upwards by following the growth of numbers on the y axis of real numbers.

The given function extends from negative infinite to positive infinite on the x axis and that is the domain of this function.

The minimum of a given function is 4, which means that the function exists from 4  upwards and that is the range of the function.

Domain; all real numbers or x ∈ ( -∞ , + ∞)

Range:  ( y ≥ 4 )

WHAT IS 3847 TIMES 4387 AND PLAESE ROUND!!!!!<br> ---------<br> 82364
Andrew [12]

Answer:

16,876,789. 82364 ≈ 82,000

Step-by-step explanation:

Let's go through this Step by Step.

3847 * 4387 =\\3847 * 7 = 26929\\3847 * 80 = 307,760\\3847 * 300 = 1,154,100\\3847 * 4000 = 15,388,000

Now let's go through the Addition.

26929 + 307,760 = 334,689\\334,689 + 1,154,100 = 1,484,789\\1,484,789 + 15,388,000 = 16,872,789

Now, we round 82364 to the nearest thousand.

The nearest thousand is 2000. so the answer to this one would be 82000.

hope this helps.
