Please help in the question it should be if t=-6 when r =-2 its an error
Natasha2012 [34]

Answer:

r = - \frac{12}{7}

Step-by-step explanation:

Given that r varies inversely as t , then the equation relating them is

r = \frac{k}{t} ← k is the constant of variation

To find k use the condition t = - 6 when r = - 2, then

- 2 = \frac{k}{-6} ( multiply both sides by - 6 )

12 = k, thus

r = \frac{12}{t} ← equation of variation

when t = - 7, then

r = \frac{12}{-7} = - \frac{12}{7}
