Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).
Answer:
x-intercept ( 18/5, 0) y-intercept: (0, -2)
Step-by-step explanation:
-5x+9y= -18
Find x-intercept by letting y = 0.
-5x + 9*0 = -18
-5x = -18
x = 18/5
Find y-intercept by letting x=0
-5*0 +9y = -18
9y =-18
y = -2

Answer:
The number N of bacteria in a refrigerated food is given by N(T) = 10T^2 - 20T + 600, 2 ≤ T ≤ 20 where T is the temperature of the food in degrees Celsius. When the food is removed from refrigeration, the temperature of the food is given by T(t) = 3t + 2, 0 ≤ t ≤ 6 where t is the time in hours.
