Answer:
I would stay direct vartation
Step-by-step explanation:
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Answer:
y = 4x - 2
Step-by-step explanation:
Tina should buy 6 packs of aa batteries and 2 packs of d batteries. the cost of each is given as.
