The slopes of perpendicular line segments are 1/3 and d/5. What is the value of d

a_sh-v [17]

If 2 lines (or line segments) are perpendicular, then the product of their slopes is equal to -1.

Thus, since the given line segments are perpendicular, we have:

$\displaystyle{ \frac{1}{3}\cdot \frac{d}{5}=-1$ .

Multiplying both sides of the equation by 15, we get d=-15.

Answer: d=-15

Determine whether the lines x+ 7y= −3 and y = 7x + 25 are parallel, perpendicular, or neither. Justify your answer by showing al

Zielflug [23.3K]

Answer:

perpendicular

Step-by-step explanation:

Rewrite the equations

y = (-1/7)x - 3/7 -- L1

y = 7x + 25 -- L2

Slope of L1 x Slope of L2 = -1/7 x 7 = -1

As a result, the two lines are perpendicular
