Replace,
x = y
Or
x = f(x)
then us stay:
x = 5y + 12
Isolate 5y
5y = x - 12
Dividing both the sides by 5
y = x/5 - 12/5
Then, replace y = f^-(x)
f^-(x) = x/5 - 12/5
Hope this helps
Answer:
The change in elevation=2,400 feet
Step-by-step explanation:
The expression to determine the change in elevation after 6 minutes is a s follows;
D=S×T
where;
D=change in elevation in feet
S=speed/ descending rate
T=time
In our case;
D=unknown
S=400 feet/minute
T=6 minutes
replacing;
D=400×6=2,400 feet
The change in elevation=2,400 feet

Answer:
Step-by-step explanation:
Plan for store 1,
y = 47 + 20x
Here y = cost of the camera
x = number of months to pay
Plan for store 2,
y = 15x + 77
If Brianna pays off the amount in 12 months,
So for x = 12 months,
For store 1,
y = 47 + (20×12)
y = $287
For store 2,
y = 15(12) + 77
y = 180 + 77
y = $257
The camera at the second store is cheaper when he camera is paid off in 12 months because the cost at the first store is $287 and cost at the second store is $257.
- "Technically, all of the choices can be written as a difference of squares. Just find the square root of both terms and use the formula.
However, I am going to assume that your problems want to know if the expressions can be written as a difference of two squares, where and are either variables with an even exponent or a perfect square, as this is what many instructors are asking for."
- "C.) We can apply it to Choice C, since g has an even exponent and 36 is a perfect square. Applying the formula, we get:
g^2 - 36 = (g + 6)(g - 6)"
(C.)g2 - 36
