For this case we have the following system of equations:

y =-x-4\\y = x

If we substitute the second equation in the first we have:

x = -x-4\\2x = -4

x=\frac{-4} {2}\\x = -2

So:

y = -2

Thus, the lines intersect at:(x, y):(-2,-2)

Answer:

See attached image

(x, y): (- 2, -2)

Find the derivative of 1/√s+2
QveST [7]

Using the quotient rule, it is found that the derivative of the function is given as follows:

f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}

<h3>What is the derivative of a quotient?</h3>

Suppose a quotient function defined as follows:

f(x) = \frac{g(x)}{h(x)}

Then, the derivative is given by:

f^{\prime}(x) = \frac{g^{\prime}(x)h(x) - h^{\prime}(x)g(x)}{h(x)^2}

In this problem, we have that:

  • g(x) = 1.
  • g'(x) = 0.
  • h(x) = \sqrt{s} + 2.
  • h^{\prime}(x) = \frac{1}{2\sqrt{s}}

Then, since g'(x) = 0, the derivative is given by:

f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}

Yes

Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

6.1 + 13.2 = 19.2

19.3 > 16.2 ✔️

6.1 + 16.2 = 22.3

22.3 > 13.2 ✔️

13.2 + 16.2 = 29.4

29.4 > 6.1 ✔️

What is the product of 6 and 2 square root of 72 in simplest radical form?
Anna [14]

Answer:

72\sqrt{2}

Step-by-step explanation:

(6) 2\sqrt{72} \\

Simplify the square root of 72 by finding perfect squares

\sqrt{9(4)(2)}

The square root of 9 = 3 and the square root of 4 = 2. Bring the 2 and 3 outside the square root.

6(2)(2)(3)\sqrt{2}

Multiply

6 x 2 x 2 x 3 = 72

72\sqrt{2}
