Answer:
They are perpendicular.
Step-by-step explanation:
When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.
Answer:
D = n/5 - m^2
Step-by-step explanation:
work:
n = 5(m^2 + D)
distribute the 5
n = 5m^2 + 5D
move the 5 to the other side by subtracting from both sides
n - 5m^2 = 5D
Divide both sides by 5 to isolate D
n/5 -m^2 = D
use reflexive property to get the answer on the left side
D = n/5 - m^2
<span>x y z are in geometric
x/y = y/z
OR y^2=xz
x^2, y^2, z^2
x^2, xz, z^2
If they are in geometric sequence then
xz/x^2 = z^2/xz
z/x = z/x
The ratios are common
so x^2,y^2 & z^2 is a GP.</span>
