swat32

Answer:

$\left(x^{2-8}\right)+\left(-2x^2\right)=\frac{1}{x^6}-2x^2$

Step-by-step explanation:

$\left(x^{2-8}\right)+\left(-2x^2\right)$

$=x^{2-8}-2x^2$

$=x^{-6}-2x^2$

What is the slope of the line that passes through the points (4, 2) and (-16, -10)?

Kamila [148]

Answer:

$\frac{3}{5}$

Step-by-step explanation:

In order to calculate the slope m between two points (x1, y1) and (x2, y2), we can use the formula below:

$m=\frac{y^{2-y^{1} } }{x^{2-x^{1} } }$

So, for points (4, 2) and (-16, -10), we have:

$m=\frac{-10-2}{16-4} =\frac{-12}{-20} =\frac{3}{5}$

Therefore, The Answer is $\frac{3}{5}$

If the domain of the coordinate transformation (, ) = ( + 2,− − 4) is (1, -4), (3, -2), (0, −1), what is the range?

timama [110]

Answer:

A. (-2, -5), (0, -7), (1, -4)

Step-by-step explanation:

The following transformation is applied:

$(x,y) \rightarrow (y + 2, -x - 4)$

To find the range:

We apply the transformation to the points in the domain. Thus:

$(1,-4) \rightarrow (-4 + 2, -1 - 4) = (-2, -5)$

$(3,-2) \rightarrow (-2 + 2, -3 - 4) = (0, -7)$

$(0,-1) \rightarrow (-1 + 2, 0 - 4) = (1, -4)$

Thus the correct answer is given by option a.
