Answer:
- x > -2
- n ≤ -2 or n ≥ 8
Step-by-step explanation:
<h3>1.</h3>
Add 7x-2 to both sides and collect terms.
2x +2 -6x +7x -2 > -4 -7x +7x -2
3x > -6
x > -2 . . . . . . . divide by 3
__
<h3>2.</h3>
Solve these one at a time, and form the union of the answers.
1 +7n ≤ 15 . . . .given
7n ≤ 14 . . . . . . subtract 1
n ≤ 2 . . . . . . . divide by 7
__
-2n -2 ≤ -18 . . . given
-2n ≤ -16 . . . . . add 2
n ≥ 8 . . . . . . . . divide by -2
The solution is n ≤ -2 or n ≥ 8.

Answer:
Both leave at 4 pm . The next time they will leave at 5:20 pm
Step-by-step explanation:
Taking LCM of 16 and 10
16= 2*2*2*2
10= 2*5
LCM= 2*2*2*2*5= 80
1 hour = 60 mins
80/60= 1 hour 20 minutes
Both leave at 4 pm . The next time they will leave at 5:20 pm
After you plug in d and C you will end up with 40 after you solve if you just need the equation it will be -2-4-3+17+32 to simplify further add like terms which will give you -9+49 add those and it’ll be 40
Answer:
Step-by-step explanation:
Given two non zero vectors, 
.
Let the angle between the two vectors = 
Given that:
Let us have a look at the formula for magnitude of addition of two vectors:
Where is the angle between the two vectors.
formula for magnitude of subtraction of two vectors:
As per the given condition:
Squaring both sides:
So, the angle between the two vectors is:
