Each day it decrease $2. So just multiply $2 x 4 days. It changed a total of $8.
Answer:
-5
Step-by-step explanation:
8/3c-2=2/3c-12
first we'll do the LCM of both sides denominator 3 and 3=3
and multiply this with both side
3×8/3c - 2×3= 3×2/3c - 3×12
8c-6= 2c-36
8c-2c=-36+6
6c=-30
c=-30/6
c= -5
Your scaling in the x direction is OK, but you didn't scale in the y direction properly. Hint. Scale each vertex of the original rectangle independently to construct the scaled rectangle.
I see the original points and their scaling by 2 as
(2,2) - Scales to (2*2, 2*2) = (4,4) OK in your drawing.
(-2,2) - Scales to (-2*2, 2*2) = (-4,4) OK in your drawing.
(2,5) - Scales to (2*2, 5*2) = (4,10) Error in your drawing.
(-2,5) - Scales to (-2*2, 5*2) = (-4,10) Error in your drawing.
B 216 because if you multiply pi with the answer you get 678.58
