D. It is not a function because there are multiple outputs for one input.
Answer:
12
Step-by-step explanation:
"ba" means "b * a", where * is multiplication. So, we want to find the product of a and b.
We know a = 3 and b = 4, so we just plug these in: 3 * 4 = 12.
Thus, ba = 12.
Hope this helps!
Multiply 10.5 and 23.5 to get 246.75. Divide that by 3 and you have your answer, 82.25.
X is 7 obiviously because when you subtract 5 from both sides you are gonna have 7 for x
