Solve using the elimination method 0.3x-0.2y=4 0.2x+0.5y=-21/23

47 - 90 = 43

43 - 180 = x

x = 137

$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.

answer: it is 8

step-by-step explanation:

you know why its 8
