Answer:
The answer is 2nd point
Step-by-step explanation:
In this question, inverse of f(x) is equals to g(x). First, you must know how to find the inverse of f(x). In order to find the g(x), you must let f(x) = y and make x thd subject :
1.
Let y = (10x+9)/8
y = (10x+9)/8
8y = 10x + 9
8y - 9 = 10x
(8y-9)/10 = x
x = (8y-9)/10
g(x) = (8x-9)/10 (Remember to convert y back to x)
2.
Let y = x - 9
y = x - 9
y + 9 = x
x = y + 9
g(x) = x + 3
Next, by looking in no.1, the inverse of f(x) is wrong and in no.2, it shows the correct form of inverse. So only 2 is an inverse function
(0.300 kW) * (24 h/day) * (30 day) * ($0.07/kWh) = $15.12
N + (n+1) = 37
n+n + 1 = 37
2n + 1 = 37
2n = 36
n = 18
n+1 = 19
18 and 19

<u><em>Answer:</em></u>
-23.4 at 9:00 a.m.
<u><em>Step-by-step explanation:</em></u>
Make a ratio with the given numbers: -13, 5.
I believe the "common number" for the ratio of 1 a.m. would be:
2.6<u> : </u>1 times 9 = 23.4<u> </u><u>:</u><u> </u>9
It is 200,000 because its ten times different
HOPE THIS HELPS!!
