Answer:
4w+12
Step-by-step explanation:
p=2l+2w
p=2w+2w+6+6
p=4w+12
6: Yes, it is linear. The constant rate of change is

, which you can make

. This simplifies to 15, so the constant rate of change is 15.
7. Yes, a proportional relationship exists because every output value is exactly three times every corresponding input value.
8. Yes, a proportional relationship exists because every output value is exactly

times the corresponding input value.
9. Yes, a proportional relationship exists because every y value is 7.5 times every corresponding x value, and if a line were to be drawn through the points, it would go through the origin (0,0).
Answer:
D
it is equivalent to the expression
Answer:
Step-by-step explanation: 18% is a fraction 
In this case since 700 18% of the budget we can do the same thing with the budget being valued as y.
Answer:
The point that maximizes the objective function is (3,0)
Step-by-step explanation:
we have
Constraints:

Using a graphing tool
The feasible region is the shaded area
see the attached figure
The vertices of the feasible region are
(0,0),(0,1),(1.5,1.5) and (3,0)
we know that
To find the point in the feasible region that maximizes the objective function, replace each ordered pair of vertices in the objective function and then compare the results.
The objective function is

For (0,0) -----> 
For (0,1) -----> 
For (1.5,1.5) -----> 
For (3,0) -----> 
therefore
The point that maximizes the objective function is (3,0)
