Answer:
No
Step-by-step explanation:
If the lines are perpendicular then they will be the negative reciprocals of each other.
Calculate the slope using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)
= 
= - 
Repeat the process with
(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)
= 
= 
The slopes are not the negative reciprocal of each other, thus they are not perpendicular.
Answer:
90 MPH
Step-by-step explanation:
2700 / 30 = 90
The answer is 7(3e+5)=7(3e+5)
<span><span>15 times 9.25 = 138.75 inches.
That leaves
144-138.75 = 5.25 inches for spaces.
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.</span>

<span>Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches
= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)</span></span>
