T(t)=70+110e^(-t/2)
After 4 minutes, t= 4
Substituting in the temperature equation,
T(4 minutes) = 70+110e^(-4/2)=70+110e^(-2) = 84.89 oF
Simply do 8/8 - 5/8
Your answer: 3/8 of the pie is left

Answer:
x = 1, y = -4
Step-by-step explanation:
7х + 2y = -1 ------ eq1
3х — 4y = 19 ------ eq2
multiply eq1 by 2
2 x (7х + 2y = -1)
14x + 4y = -2 -----eq3
by elimination, add equation 2 and 3
14x + 3x = 19-2
17x = 17 (divide both sides by 17)
x = 1 (answer)
substitute into eq1
7(1) + 2y = -1 (subtract 7 from both sides)
2y = -1 -7
2y = -8 (divide both sides by 2)
y = -8/2 = -4 (answer)
