Answer:

$100x^{4}y^{6}$

Step-by-step explanation:

$(25xy^{3} )(4xy)(x^{2}y^{2})$

Austin pays $2 per day for high speed internet. The equation y = 2x relates his internet charges (y) to the number of days (x) h

Alika [10]

Answer:

Option C. 2

Step-by-step explanation:

Let

x ----> the number of days

y ----> the internet charges in dollars

we have

$y=2x$

This is a proportional relationship between the variables x and y

The slope of the linear function is equal to the constant of proportionality k

$k=m=2\frac{\$}{day}$

The unit rate is the same that the slope

The unit rate is $2 per day

therefore

The unit rate in the equation is 2
