Answer:

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the 2 other sides, that is

x² + 6² = 17²

x² + 36 = 289 ( subtract 36 from both sides )

x² = 253 ( take the square root of both sides )

x = $\sqrt{253}$ → C

Answer:

The coordinates of the midpoint of the two vertices are

(0,2) (Third option)

Step-by-step explanation:

<u>Coordinates Of A Midpoint </u>

Given a pair of points in the plane

$\displaystyle P_1\ (x_1,y_1)\ ,\ P_2(x_2,y_2)$

the coordinates of the midpoint of both points are

$\displaystyle x_m=\frac{x_1+x_2}{2}$

$\displaystyle y_m=\frac{y_1+y_2}{2}$

The vertices given in the figure are

$\displaystyle v_1(-4,1),\ v_2\ (4,3)$

So the x-coordinate of their midpoint is

$\displaystyle x_m=\frac{-4+4}{2}=\frac{0}{2}=0$

And the y-coordinate of their midpoint is

$\displaystyle y_m=\frac{1+3}{2}=\frac{4}{2}=2$

So the coordinates of the midpoint of the two vertices are

(0,2), the third option

What is the slope of a line parallel to 5x-3y=-10

Llana [10]

For parallel lines, slopes are equal.
5x - 3y = -10
3y = 5x + 10
y = 5/3 x + 10/3

Required slope = 5/3
