The answer is 5 because first, you make the expression 15/6*7-39 then simplify so that it becomes 15/42-39 simplify again to get 15/3 which equals 5
Answer:
The domain of f is x > 0.
The range of f is all real numbers.
The domain of the inverse function is all real numbers.
The range of the inverse function is y > 0.
The domain of f is the same as the
range of the inverse function.
The range of f is the same as the
domain of the inverse function.

Answer:
$13.50
Step-by-step explanation:
30 - (11.90 + 4.60) = 30 - 16.50 = 13.50
No because they do not have the same factors
Let candy bars =xLet drinks =y Set up the two equations. 60x + 110y = 265120x + 90y = 270 Solve through elimination. Multiple the first equation by 2 and subtract the second equation from the first. When we multiply the first equation by two, we get: 2(60x +110y = 265) = 120x + 220y = 530 Then, when we subtract the second from the first we get: (120x + 220y = 530) - (120x +90y = 270) The result is 130y = 260 So, y=2 Then, we plug that back in to the original equation to find x. 60x + 220 = 265 Subtract 220 from both sides. 60x = 45 x = .75 So, drinks cost 2 dollars and candy bars cost 75 cents.
Hope this helps! :)
