Answer:
wher is question
Step-by-step explanation:
Inorder to the line, choose 2 y-intercepts, for example y1=0 and y2=1, then substitute each of them in the equation.
for y1 = 0:
0 + 1 = -3/5x + 12/4
3/5x = 12/4 - 1
3/5x = 2
x1 = 10/3
A(10/3;0)
for y2 = 1
1 + 1 = -3/5x + 12/5
3/5x = 12/5 - 2
3/5x = 2/5
x2 = 2/3
B(2/3;1)
Place the two resulting points exactly on the plane, and match them, then prolong the line.

Answer:
k ≈ -0.06729
Step-by-step explanation:
The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.
k = ln(35/49)/5 ≈ -0.06729
__
The equation for the temperature T of the can in the refrigerator is ...
T = 49e^(-0.06729t) +36
_____
<em>Additional comment</em>
Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.
