Hello! Could you please help with these? It was due quite a long time ago. I have a D in this class and need to get my grades up.

16.

17.

18.

19.

Step-by-step explanation:

Equation is where k is a constant of proportionality.

16.

So, equation is

17.

Equation is

18.

Equation is

19.

Equation is

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
