It's saying that the polynomial can be factored into a perfect square (x + 5)(x+5) because when you multiply it, you get x² + 5x + 5x + 25 or x² + 10x + 25 so the factored form can be rewritten as (x + 5)² because it can be multiplied by itself to get the polynomial listed, so a = x and b = 5

Assume that y varies inversely with x. If y= 1.6 when x= 0.5, find x when y= 3.2

solniwko [45]

Answer:

x = 0.25

Step-by-step explanation:

If y varies inversely with x, then:

$y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x} \quad \textsf{(for some constant k)}$

Given:

y = 1.6 when x = 0.5

Substitute the given values into the found equation and solve for k:

$\implies 1.6=\dfrac{k}{0.5}$

$\implies k=1.6(0.5)$

$\implies k=0.8$

Therefore:

$y=\dfrac{0.8}{x}$

To find the value of x when y = 3.2, substitute y = 3.2 into the found equation and solve for x:

$\implies 3.2=\dfrac{0.8}{x}$

$\implies x=\dfrac{0.8}{3.2}$

$\implies x=0.25$
