Answer:
(8, 72)
Step-by-step explanation:
Here we have two separate equations for y: y = 9x and y = 2x + 56.
Equating these equations eliminates y temporarily; we get:
9x = 2x + 56, or 7x = 56. Dividing both sides by 7 results in x = 8.
Then, by the first equation, y = 9(8) = 72.
The solution is (8, 72).
P = 2(L + W)
P = 292
L = 5W - 4
292 = 2(5W - 4 + W)
292 = 2(6W - 4)
292 = 12W - 8
292 + 8 = 12W
300 = 12W
300/12 = W
25 = W <=== width is 25 ft
L = 5W - 4
L = 5(25) - 4
L = 125 - 4
L = 121 <=== length is 121 ft
Answer:
The answer is below
Step-by-step explanation:
The electrical resistance R of a wire varies inversely with the square of its diameter d:
R ∝ 1 / d
Let k represent the constant of proportionality, hence we can represent the statement as an equation:
