Answer:
The parallel line has slope 
The perpendicular line has slope 
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:

Placing it in the general format


So this line has slope 
Parallel line:
Same slope, so the parallel line has slope 
Perpendicular line:
Multiplication of the slopes is -1. So



The perpendicular line has slope

Answer:
Christopher is 24 years old now
Step-by-step explanation:
I honestly don't know how I got my answer but I know it's correct
So 12 = 2 + 20t -5t^2
5t^2 -20t + 10=0
t^2 -4t + 2 = 0
Use quadratic formula to solve
Answer:
0.225
Step-by-step explanation:
Total outcomes of choosing 5 out of 18 members = 18C5
Outcomes of choosing 2 out 11 favourers, 3 out of 7 members = 11C2 & 7C3
Probability = Favourable outcomes / Total outcomes
= ( 11C2 x 7C3 ) / 18C5
<u>[ { 11 ! / 2! 9! } {7 ! / 3! 4! } ] </u>
[ 18 ! / 5! 13! ]
( 55 x 35 ) / 8568
1925 / 8568
= 0.2246 ≈ 0.225
