Step-by-step explanation:
2(sp)=ln
6x+2=10x-6
8=4x
x=2
therefore sp=3×2+1=6+1=7
Option D
Answer:
x=4
Step-by-step explanation:
3x = 12
divide by 3
x =12/3
1345 - (-853) = D) 2198.
Simplify your brackets to get: 1345 + 853 and then add which will get you your answer, 2198.
Answer:

Step-by-step explanation:
Given

Rotation = +270 degrees
Required
Determine the new coordinates of Q (i.e. Q')
When a point (x,y) is rotated +270° about the origin, the new coordinates is: (y,−x)
So:

Where:
and 
Q' will be:
