Step-by-step explanation
Here ...I'm not too sure about the question as you have written
P = 2 ( 1 + 6 ) and ask to solve for L ...
.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.
...So let me correct the question....
P = 2 ( l + 6 )
P = 2l + 12
P - 2l = 12
- 2l = 12 - P
- 2l = - P + 12
Change the sign of both side of the equation...
2l = P + 12
divide both side by the same number...
L = ( P + 12 ) ÷ 2

Calculate the product of rational numbers...

For direct variation:
y = kx

k = 9/12 = 3/4
Answer:

Step-by-step explanation:
Use coordinates (2,1) and 3,10
The exponential equation is

Plug in the x and y values.xfor both functions of coordinates.


Divide the equation with the larger exponet by the other equation.

Substitute that in for one of the equations.

Solve for a.


So our exponetial equation is
