Let f(x) = -2x + 7 and g(x) = -6x + 3. Find fog and state its domain.

y=12x-39

Step-by-step explanation:

it's linear equation so the domain is real number

a is the right answer

$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
