Answer:
D is the answer,that is the incorrect inverse function.
Step-by-step explanation:
For the first one
g(x)=6x-1
Let y=6x-1
6x=y+1
x=y+1/6
Therefore the inverse equation will be
x+1/6 so,the first equation is right.
The second one
g(x)=19x+4
Let y=19x+4
19x=y-4
x=y-4/19 so,the second function is right.
For the last one
f(x)=x/x+20
y=x/x+20
y(x+20)=x
x+20=x/y
x=x/y-20
g(x)=x/y-20,so the function is wrong and that is the aswer.
Answer:
I think the answer is y = 3x - 10
Step-by-step explanation:
in this case, we are looking at a length × width equation. this equation gives you the area of the gym. so the answer is B.
Answer:
21600 letters
Step-by-step explanation:
There are 5400 seconds in 1.5 hr, so there are 135 40-second intervals. So, 160 messages multiplied by 135 time intervals is 21600 letters.
