Answer:

after 52/3 hours

temparature will be at -151/3

Step-by-step explanation:

y = -2.5x - 7

y = -4x + 19

-2.5x - 7 = -4x + 19

4x - 2.5x = 19 + 7

1.5x = 26

1.5x = 26

3/2x = 26/1

2/3 x 3/2x = 26/1 x 2/3

x = 52/3

y = -4x + 19

y = -4(52/3) + 19

y = -208/3 + 19

y = -208/3 + 19/1

y = -208/3 + 57/3

y = -151/3
