For this case, we observe that the dispersion diagram has a behavior similar to a straight line.
we observe that as the values of x increase, the values of y decrease.
Therefore, the line is of negative slope.

Write as a product: −y^3+xy^2−4x+4y

Semmy [17]

Answer:

$(x-y)\left(y^{2}-4\right) \text { is the product of }-y^{3}+x y^{2}-4 x+4 y$

Step-by-step explanation:

$\text { Given equation is }-y^{3}+x y^{2}-4 x+4 y$

$\text { Writing all }^{a} x^{\prime \prime} \text { terms and "y" terms at a place. }$

$\left(-4 x+x y^{2}\right)+\left(4 y-y^{3}\right)$

Now take “x” common in the first term and “y” common in second term then the equation becomes as follows:

$x\left(-4+y^{2}\right)-y\left(-4+y^{2}\right)$

$x\left(y^{2}-4\right)-y\left(y^{2}-4\right)$

$(x-y)\left(y^{2}-4\right)$

$\text { The product of the given equation is }(x-y)\left(y^{2}-4\right)$

4x2 + y2 = 36 Obtener dominio

Veronika [31]

Answer:

[-3,3]

Step-by-step explanation:

Write the problem as a mathematical expression.

4x^2+y^2=36

Subtract 4x^2 from both sides of the equation.

y^2=36-4x^2

Take the square root of both sides of the equation to eliminate the exponent on the left side.

y= + and - $\sqrt{36-4x^2}$

The complete solution is the result of both the positive and negative portions of the solution.

y= $2\sqrt{(3+x)(3-x)$

$y= -2\sqrt{(3+x)(3-x)}$

Set the radicand in $\sqrt{(3+x)(3-x)} \geq 0$ greater than or equal to 0 to find where the expression is defined.

$(3+x)(3-x)\geq 0$

So your answer would be [-3,3]

What is the answer to this?

katrin [286]

Answer:

$\huge\boxed{-28}$

Step-by-step explanation:

We can substitute the given values of $a$ , $b$ , and $c$ to find the value of this expression.

$-4 | a + b - c|$

$-4 | 3 + (-2) - (-6)|$

We know that two negatives make a positive. This means that $-2 - (-6)$ will be the same this as $-2+6$

$-4 | 3 + -2 + 6|$

Adding a negative is the same as subtracting a positive.

$\4 | 3-2+6|\\\\3-2+6 = 7$

$-4 \cdot 7 = -28$

Hope this helped!

Brian is skateboarding at 8 kilometers per hour. How long will it take Brian to travel 12 kilometers?

brilliants [131]

Answer:

An hour and 30 minutes.

Step-by-step explanation:

In one hour, they travel 8 kilometers. They then have 4 kilometers left. 4 is half. of 8, so I would possibly take half the time it would to travel 8, making it 30 minutes for the other 4 kilometers.
