Answer:
The temperature in Duluth is closer to zero
Step-by-step explanation:
-29,-28,-27,-26,-25,-24,-23,-22,-21,-20,-19,-18,-17,-16,-15,-14,-13,-12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31
-29<31
Duluth
The temperature in Duluth is closer to 0 degrees.
Try to think of these two numbers on a number line.
-29 degrees is 29 points away from 0 → -29 + 29 = 0
However, 31 degrees is 31 points away from 0. If you subtract Duluth's temperature from St. Louis's temperature, you get 2.
31 + (-29) = 2
Since Duluth's temperature would be exactly zero degrees and St. Louis's temperature would be two degrees from zero, Duluth is closer to zero degrees.
Hope that helps.
y = 120x
y=mx + b is what we need where m is the slope and b is the y-intercept.
the train travels at about 120km/hour, thus the slope is 120.
y= 120x +b. to find the y intercept plug in any coordinate.
240 = 120(2) +b. you find that the y-intercept is 0.
final equation: y= 120x
0.75 or 3/4
f(-2) = 3•2^-2
f(-2) = 3•0.25
f(-2) = 0.75 or 3/4
