Answer:
The graph of the inverse function is the same that the graph of the original function
Step-by-step explanation:
step 1
Find the equation of the function in the graph
Let
f(x) ---> the function in the graph
we know that
Is a linear function
take the points (0,6) and (6,0)
<em>Find the slope of the linear function</em>

<em>Find the the equation of the linear function in slope intercept form</em>

we have

---> the y-intercept is given
substitute

step 2
Find the inverse of the function f(x)
Let
y=f(x)

<em>Exchange the variables (x for y and y for x)</em>

Isolate the variable y

Let



In this problem the graph of the inverse function is the same that the graph of the original function
Answer:
Her pin must be 1147
Step-by-step explanation:
A little trick I have up my sleeve when I have these kind of questions is that I find the square root of each number, then find what is prime.

Since the only prime numbers in the range of 31 and 38 is 31 and 37.
We can then multiply 31 by 37 to get 1147.
Answer: p=0.87 (density of oil), m=37.5 (mass of liquid), v=11.92 (volume of liquid)
Step-by-step explanation:
p=m/v
p=43.5/50
p=0.87 (density of oil)
m=pv
m=2.5x15
m=37.5 (mass of liquid)
v=m/p
v=65/5.45
v=11.93 (volume of liquid)
