The answer is:
The slope is: 4
The y-intercept is: 3
The explanation is shown below:
1. The slope intercept form of the linear equation is:
Where 
is the slope and 
is the y-intercept.
2. Therefore, you must solve for <em>y</em>, as following:
Answer:: D(t)= 50(4/5)^t
Step-by-step explanation: If 1/5 of the temperature difference is lost each minute, that means 4/5 of the difference remains each minute. So each minute, the temperature difference is multiplied by a factor of 4/5 (or 0.8).
If we start with the initial temperature difference, 50° Celsius, and keep multiplying by 4/5, this function gives us the temperature difference t minutes after the cake was put in the cooler.
Answer:
Step-by-step explanation:
Set up an equation and solve for r using the formula for slope:
Answer:
888+88+8+8+8
Step-by-step explanation:
Answer:
2y = 3x - 8
y = 3/2x - 4
Work
-2x + 5(3/2x - 4) = -9
-2x + 15/2x - 20 (+20) = -9 (+20)
-4/2x + 15/2x = 11
11/2x * (2/11) = 11 (2/11)
x = 2
3(2) - 2y = 8
6 (-6) - 2y = 8 (-6)
-2y = 2
y = - 1
final answer:
x = 2
y = -1
