Answer:

Step-by-step explanation:

Hint:

a² - 9a + 15 = (a-7)(a-2)

a² + 9a + 15 = (a+7)(a+2)

a² + 3a - 10 = (a-2)(a+5)

a² + 5a - 14 = (a-2)(a+7)

a² - 5a - 14 = (a-7)(a+2)

Answer gets BRAINLIEST If q varies inversely as r, and g = 10 when r = 2.5, find the equation that connects a

vladimir1956 [14]

Answer:

Step-by-step explanation:

In direct variations, we would have:

$q=kr$

Where k is some constant.

Since this is indirect variation, instead of that, we would have:

$q=\frac{k}{r}$

To determine the equation, find k by putting in the values for q and r:

$10=\frac{k}{2.5}\\k=2.5(10)=25$

Now plug this back into the variation:

$q=\frac{25}{r}$

The answer is D.
