Answer:
20
Step-by-step explanation:
20 is divisible by 4, 5 and 10
Answer:
equation: y = -6x -20
Step-by-step explanation:
pass (0,-20) (-10,40)
y = mx + b
y intercept (b) = -20
slope (m) = (40 - -20) / (-10 - 0) = 60 / -10 = - 6
equation: y = -6x -20
The temperature 6 hours after day break is 53 degrees
Step-by-step explanation:
The temperature was 65 degrees at daybreak. Then it dropped two degrees per hour until dusk. This decrease in temperature can be modeled by the equation,
y = -2x + 65
according to this equation
y= temperature after day break
x= no of hours ( in this case 6)
So equation becomes
y= -2 (6) +65
y= 65- 12
y= 53 degrees
So the temperature 6 hours after day break is 53 degrees
