For the linear model, y = -67.9x +679, the distance, in miles y, is a function of time, x, in hours. use the model to calculate the total distance, in miles, at x = 2 hours. cannot be determined 10 miles 543.2 miles 814.8 miles

x = 2

 replace x with 2:

y = -67.9(2) +679

y = -135.8 + 679

y = 543.2

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
