Answer:
P = - 1
Step-by-step explanation:
Given P varies inversely with x the the equation relating them is
P = 
← k is the constant of variation
To find k use the condition P = 12 when x = 4
12 = 
( multiply both sides by 4 )
48 = k
P = 
← equation of variation
When x = - 48, then
P = 
= - 1
Answer:
4w+10=-w
w=-2
Step-by-step explanation:
First, write out the equation in the algebraic form to make it easier to solve. This equation written out is 4w+10=-w. Then, isolate the variable and solve. Do this by subtracting 4w from both sides. Then, divide both sides by -5.
Answer:
s^4/r^2
Step-by-step explanation:
r^-2/ s^-4
When the exponent is negative, it moves from the numerator to the denominator or from the denominator to the numerator
r^-2 becomes 1 /r^2
1 / s^-4 becomes s^4
r^-2/ s^-4 = s^4/r^2
