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

Answer:
y = 60
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 10, then
20 = 10k ( divide both sides by 10 )
2 = k
y = 2x ← equation of variation
When x = 30, then
y = 2 × 30 = 60
