Answer:
they saved $10.29
Step-by-step explanation:
Y = mx + b
slope(m) = 7
(1,8)...x = 1 and y = 8
now we sub into the formula and find b, the y int
8 = 7(1) + b
8 = 7 + b
8 - 7 = b
1 = b
so ur equation is : y = 7x + 1 <==
Answer:
No. two inputs cannot have the same output
Step-by-step explanation:
This is not a function because -2 and 2 have the same output which is 4
HOPE THIS HELPS :)

Step-by-step explanation:
Answer:
f(x) and its inverse are the same
Step-by-step explanation:
<u>The inverse function
</u>
If y=f(x), the inverse function 
is defined such as
To find the inverse function, there is a practical method:
a) Change letters x for y and vice-versa
b) Isolate y in terms of x only
c) 
In our case, 
a) Interchanging letters
b) Isolate 
c) 
As we can easily see, f and its inverse are exactly the same
