What is the length of xy?

Sav [38]

Given:

$XR=x+8$

$RY=4x-10$

Since R is the midpoint of the line, we can set XR equal to RY and solve for x.

$RY=XR$

$4x-10=x+8$

$4x=x+18$

$3x=18$

$x=6$

Now we know what x is. We can plug in x to RY and XR and then add it all together to find XY. Let's find XR:

$XR=6+8$

$XR=14$

Let's find RY now:

$RY=4(6)-10$

$RY=24-10$

$RY=14$

Since we know that:

$XR+RY=XY$

We can plug in our answers:

$14+14=XY$

Final answer:

$XY=28$

What is the slope between the points (2, 3) and (-1, 12)

Scrat [10]

Answer:

$\huge \boxed {slope = - 3}$

Step-by-step explanation:

$m = \frac{rise}{run}$

The slope is the change of y over the change of x.

$m = \frac{12 - 3}{ - 1 - 2} \\ m = \frac{9}{ - 3} \\ m = - \frac{9}{3} \\ m = - 3$

Therefore, the slope is -3.
