Answer:
P1= -2/3
P2= -10/3
Step-by-step explanation:
take the sq rt of both sides and use both + and - roots
3P+6=4
3P+6=-4
subtract 6 from both sides for each one
3P=-2
P=-2/3
3P=-10
P= -10/3

Answer:
Step-by-step explanation:
When "y varies directly with x" this means that:
where k is a number we need to find out (called the constant of proportionality if you care about that).
We can figure out what k is because they tell us when y= -252, x=84. Substituting those values into our equation we get:
and therefore:
.
So our equation or formula between y and x is:
.
So when x = 74, then:
