Answer:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = ( multiply both sides by 8 )
56 = k
P = ← equation of variation
When x = 7 , then
P = = 8
Answer:
f(3) = 4
f(-7) = -26
Step-by-step explanation:
Hi there!
To find f(3), replace every x with 3:
Therefore, f(3)=4.
To find f(-7), replace every x with -7:
Therefore, f(-7)=-26.
I hope this helps!
