7 Find the values of k such that the straight line y = 2x +k meets the curve with equation
x2 + 2xy + 2y2 = 5 exactly once.

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
