Millimeter centimeter meter kilometer
slope = (y2-y1)/(x2-x1)
= (70-52)/(8-1)
= 18/7
=2.6
point slope form
y-y1 = m(x-x1)
y-52 = 2.6(x-1)
distribute
y-52 = 2.6x-2.6
add 52 to each side
y = 2.6x+49.4
y = 2.6x +49
the initial temperature is 49.4 or about 49
and it increases about 2.6 degrees each week
Answer:
Part 1 .
As per the given statement: In t hours the train has traveled s miles.
Distance of the train = s mile
Time = t hours
Formula for :
Speed of the train(v) = 
or
mph .....[1]
Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;

Therefore, the speed of the train(v) is, 60 mph
Part 2.
Similarly,
The formula for speed of the train (v) is given by;

Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;

Therefore, the speed of the train(v) is, 90 mph
Answer:
C is correct, D might be correct if you forgot 000 at the end of the question.
Step-by-step explanation:
005 = 5x1 so A is incorrect
945 = 9x100 + 4x10 + 5x1 so B is incorrect
15.859 = 1x10 + 5x1 + 8/10 + 5/100 + 9/1000 + so C is correct
973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect
okay idk if im right but...i think...units of measure means means like are feet,miles,kilomoters,cenimeters.
i think...hope this helps,theres a good chance im wrong
