Answer:

y = 4x + 32

Step-by-step explanation:

Given: Temperature at sunrise = 32°F

y is the temperature after x hours of sunrise

Temperature change is 4°F/hour.

The equation of a line in slope intercept form is given by

y = mx +c

where m is the slope, which is the change in value of y to the value of x

and c is the value of y at x = 0

At sunrise, x =0 and y =32

∴ c = 32

Also we see that the change in temperature to that of time is 4/1 = 4

∴ m = 4

Substituting the values of m and c in the equation of line, we have

y = 4x +32

tom took a trip of 1,020 miles. he traveled by train at 55 miles an hour and the same number of hours by plane at 285mph how man
Kamila [148]
D = vt

Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020

So, you do:
distance traveled by plane + distance traveled by train =  total distance
(55t) + (285t) = 1020

Solve for t
t = 3 hours

t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane

Total time  = 3 + 3 = 6 hours
