<h3>Answer:</h3><h3>10 < x < 42</h3>

==================================================

Explanation:

Given a triangle with sides a and b, the third side c is bounded by this compound inequality

b-a < c < b+a

where a < b

--------

In this case, a = 16 and b = 26, so

b-a < c < b+a

26-16 < x < 26+16

10 < x < 42

I'm using a version of the triangle inequality theorem.

This unknown third side is between 10 cm and 42 cm. The third side cannot equal 10 nor can it equal 42.

Find the value of k so that the graph of 13y + kx = 4 and the line containing the points (5, -8) and (2, 4) are parallel.

guajiro [1.7K]

the graph of 13y + kx = 4 and the line containing the points (5, -8) and (2, 4) are parallel.

We find the slope of parallel line using two given points

(5, -8) and (2, 4)

Slope formula is

$slope = \frac{y_2-y_1}{x_2-x_1}$

$slope = \frac{4-(-8)}{2-5}$

$slope = \frac{12)}{-3}=-4$

so slope = -4

Slope of any two parallel lines are always equal

Lets find the slope of the equation 13y + kx = 4

Subtract kx on both sides

13 y = -kx + 4

Divide both sides by 13

$y= \frac{-kx}{13} + \frac{4}{13}$

Now slope = -k/13

We know slope of parallel lines are same

So the slope of 13y + kx = 4 is also -4

Hence we equation the slope and find out k

$\frac{-k}{13}=-4$

Multiply by 13 on both sides and divide by -1

k = 52

the value of k = 52
