-2 [7+6. (-2)]
-2.(7-12)
-2.-5
10
For #18
you would divide 3y over 3 witch would cancel out then you would divide 9.5 over 3 and you would get (3.16) i think
The mean is the average, so add all the numbers and divide by 7 (7 terms).

The mean is -2.
Answer:
First option: 3 blocks to the right, 5 blocks down
Step-by-step explanation:
Answer:
Below
Step-by-step explanation:
sin(2x) = 2 ×cos(x)× sin(x)
● sin(x) = 2 × cos(x) × sin(x)
● 2 × cos(x) = 1
● cos (x) = 1/2
So we can deduce that:
● x = Pi/3 + 2*k*Pi
● or x = -Pi/3 + 2*k*Pi
K is an integer
