SOLUTION: p=3.5x-y what is the value of p when x=12 and y=5

Question 1152428: p=3.5x-y what is the value of p when x=12 and y=5

Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
p = 3.5 * x - y
when x = 12 and y = 5 then:
p = 3.5 * 12 - 5
solve for p to get:
p = 37.
you are replacing x with 12 and y with 5 in the equation.
the function p is dependent on the value of both x and y.
in functional notation, if would probably be shown as p(x,y) = 12 * x - y
the arguments to the function p are the variables x and y.
any change in either of those values will change the value of p.
for example:
the function is p = 3.5 * x - y
when x = 12 and p = 0, then p = 3.5 * 12 = 42.
when x = 12 and y = 1000, then p = -958.
when x = 0 and y = 1000, then p = -1000.
