F(1) = -2
hope it helps
---------------------------------
You have to find 80% of 20.
Since 80% is equal to 0.8, you multiply 20 by 0.8 to get 16
In the second step you should have subtracted the 2x to move it to the other or side of the equals sign
T has 4 times what R has, so 2.105*4 which is 8.42
Answer:
The numbers should be A. 5 and C. 0.
