Answer: 31
step by step solution: so the function is b(x)=x+41. they want to know what the function would equal when b(-10). so b(-10) means that you would plug (-10) in for x in the function so the function would now be b(x)=(-10)+41. now all you have to do is simplify the function. b(x)=31. so the function b(-10)=x+41 equals 31. hope this helped!!! have a great day.
Answer: $3.30
Explanation:
You set up a proportion where
9.25 X
------ = -----
2.8 1
Then you cross multiply and see that...
2.8X = 9.25
Then X = 9.25 / 2.8 = 3.30
