3 is constant
Step-by-step explanation:
3 is constant because it cannot change
Answer: B-A
Step-by-step explanation:
We know that it is -A - (-B)
The negative sign on the A stays as it is, eliminating choices A-B and A+B.
For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.
Therefore, the answer is -A+B, or B-A. Hope it helps!
Answer:
no
Step-by-step explanation:
22 - 4.5x + 36= 202 - 7.5x - 70
-4.5x + 58 = 132 - 7.5x
3x + 58 = 132
3x = 74
x = 74/3
F(2)= 5(2)-7
10-7=3
