Answer:what equation ?
Step-by-step explanation:
Answer:
The pressure is 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
In this problem we have

where
V is the volume of a gas at a constant temperature
P is the pressure
we have
For
,
step 1
Find the value of k
substitute the values of V and P


The equation is equal to 
step 2
Find the pressure when the volume is 125 cubic inches
For 
substitute in the equation and solve for P


Answer:-31/15
Step-by-step explanation: step 1: make both fractions improper
step 2: multiply numerator and denominator 31/6 x -2/5= -62/30
step 3: simplify -31/15
Perpendicular = opposite sign and reciprocal slope
2 slope turns into -1/2
Y = -1/2x + b
Plug in point
-1 = -1/2(6) + b
-1 = -3 + b, b = 2
Solution: y = -1/2x + 2
