Answer: A) max at (14, 6) = 64, min at (0,0) = 0
<u>Step-by-step explanation:</u>
Graph the lines at look for the points of intersection.
Input those points into the Constraint function (2x + 6y) and look for the maximum value and minimum value.
Points of Intersection: (0, 0), (17, 0), (0, 10), (14, 6)
Point Constraint 2x + 6y
(0, 0): 2(0) + 6(0) = 0 Minimum
(17, 0): 2(17) + 6(0) = 34
(0, 10): 2(0) + 6(10) = 60
(14, 6): 2(14) + 6(6) = 64 Maximum
Answer:
260 nesting turtles were at this sanctuary last year
Step-by-step explanation:
Given:
The number of nesting turtles decreased = 10%
Number of turtles present in sanctuary this year = 234
To Find:
Number of nesting turtles present at this sanctuary last year= ?
Solution:
Let the number of nesting turtles present at this sanctuary last year be x
Then,
x- 10% of x = Number of turtles present in sanctuary this year
x- 10% of x = 234
x= 260
