Since Density = mass/ volume (d = m / v), and assuming the 15 fish weigh 1 gram each - if weight of each fish isn't given - (making that a total of 15 grams),

D = m / v
0.3 = 15 / v
v = 15 / 0.3 = 50 ft cubed

Hope this answers your question correctly :)

Answer:

(a) y = -4x + 4 (b) y = 2x + 3

<u>solving steps:</u>

note: m refers to slope and y₁ to y point and x₁ to x point

coordinates: (2,-4)

slope: -4

equation:

y - y₁ = m(x - x₁)

y - -4 = -4(x-2)

y = -4x + 8 - 4

y = - 4x + 4

coordinates: (1,5), (-1,1)

slope: $\sf \dfrac{y-y_1}{x-x_1}$

$\sf \dfrac{1-5}{-1-1}$

equation:

y - y₁ = m(x - x₁)

y - 5 = 2(x - 1)

y - 5 = 2x - 2

y = 2x - 2 + 5

y = 2x + 3
