Determine the number of real solutions for each of the given equations. Number of solution options (no real solutions, one real solution, two real solutions)

Equations:
y = -3x^2+x+12
y = 2x^2-6x+5
y = x^2+7x-11
y = -x^2-8x-16

the answer is 15% decrease

$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

answer: 800
