Two lines are perpendicular if and only if the product of their slopes is - 1.

So, you just need to find the slope of each line and find out the product of their slopes.

I will do one example for you.

L1: y = 3x + 5

L2: y = - 3x + 14

L3: y = -x/3 + 14

The slope of a line is the coefficient of the x.

So the slopes are:

L1: slope 3
L2: slope -3
L3: slope -1/3

So now multiply the slopes of each pair of lines:

L1 and L2: 3 * (-3) = - 9 => No, they are not perpendicular

L2 and L3: (-3) * (-1/3) = 1 => No, they are not perpendicular

L1 and L3: (3) *  (-1/3) = -1 => Yes, they are penpendicular.

Find the measure of the angle that is 15x.
Naddika [18.5K]
15x would be the vertical angle of 16x -8 and since vertical angles are equal, then 15x = 16x -8.

15x = 16x -8
x = 8 and so the angle 15x = 15 * 8
which equals 120 degrees.

Who can help me with these questions
damaskus [11]
#15(A)
First Bike
$380 - $190 ($380 * 0.50) = $190

2nd Bike
$380 - $114 ( $380 * 0.30) = $266
$266 - $53.20 ($266 * 0.20) = $212.80

#15 (B)
Eliza should buy the first bike because it is cheaper. $190 < $212.80

#16
$57 + $28.50 ($57 * .50) = $85.50

What is the sum of all measures of the interior angles of a regular pentagon?
Ugo [173]
There are 540 degrees total in the interior angles of a regular pentagon.

Just so you know, the total degrees of interior angles goes up by 180 degrees.

A triangle is 180 degrees, a quadrilateral 360, and a pentagon 540.
