The answer 10x+7.5y=420 is 56
Answer:
a = 8
Step-by-step explanation:
- 2a - 5 = a + 3
- a - 5 = 3
- a = 8
Answer:
the answer is 7
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
Domain is , and when . So the range is , that is,
Inverse function:
Exchanging x and y
The inverse function is
Domain:
Range of the original function is , so the domain of the inverse function is . The correct answer is given by option B.
Answer:
2 x = y + 7
y = 2 x - 7
Step-by-step explanation:
because you can rewrite it as:
2 x - y - 7 = 0
then you can find the 2 X answer and fill that in to find y
