The temperature in Chicago is dropping at a rate of 1 degree every 4 hours when it was 10 degrees outside. The temperature in Pittsburgh was increasing at a rate of 3 degrees every 4 hours when it was 2 degrees outside. How long will it take the two cities to reach the same temperature? What is the temperature at that time?

Chicago after 8 hrs it dropped to 8 degrees and at pittsburgh after 8hrs passed it reached to 8degrees outside

so after 8hrs the cities reached the same temperature which is 8degrees

Step-by-step explanation:

10-1=9 then 9-1=8

1= each degree that dropped every 4 hours

an altitude of 15,000 feet

step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
