The statement "<span>The rate of change of y with respect to x is inversely proportional to y^4" can be written mathematically as dy/dx = k/y^4
To solve the differential equation, we use variable saparable method.
y^4 dy = kdx
Integrating both sides gives,
y^5 / 5 = kx + A
y^5 = 5kx + 5A = Bx + C; where B = 5k and C = 5A

Answer:
25/2 I believe
Step-by-step explanation:
(15 is your answer)
Divide numerator by denominator, cancel out any common factors
2x + 7 = 3
2x = 3 - 7
2x = -5
x = -5/2
