The general solution of <span>y' + 2xy = (x^3) is y(x) = c1e^(-x^2)
The general solution of </span><span>ydx = (y(e^y) - 2x)dy is x = c1/(y(x))^2 + (e^y(x) ((y(x))^2 - 2y(x) + 2)/(y(x))^2
</span>
The general solution of<span> (dP)/(dt) + 2tP = P + 4t - 2 is P(t) = c1e^(t - t^2) + 2</span>
Answer:
a-5b = 8
a = 8+5b ⇒ this is the solution
Answer:
6.5%
Step-by-step explanation:
sales price x sales tax rate = sales tax
156.50 x sales tax rate = 10.17
sales tax rate = 10.17/156.50
sales tax rate = .065 or 6.5%

$20 original = $5 final paid as $15 was s/p before -10 was added
$30 original = $14 final price as $24 was s/p before -10 was added
$60 original = $35 final price as $45 was s/p before -10 was added
$92 original = $69 final price as $59 was s/p before -10 was added
Step-by-step explanation:
Ans in bold
A) = f(x) = 20(0.75) -10 = 15 - 10 = $5 = £5 final paid
B)= f(x) 30 (0.75) = 24 - 10 = 14 = $30 original price
C) = f(x) = 60(0.75) -10 = 45 -10 = $35 = $35 final price
D) = f(x) = 92 (75) = 69 -10 = $59 = $92 original price
Yes it is a rational number it can be expressed as a fraction
