Answer:

y=3.15

Step-by-step explanation:

I am assuming you meant 2.8y in your equation.

Plug in for x

6.4(3)+2.8y=44.4

6.4*3=19.2

So now 19.2 + 2.8y = 44.4

44.4-19.2=25.2

25.2/2.8=3.15

Meaning Y=3.15

Explain the difference between linear and exponential models. How can you determine if a function is linear or exponential from
oksano4ka [1.4K]
In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier—it will never be the same, but there will be a pattern.
