Answer:
b
Step-by-step explanation:
to determine which point is a solution, substitute the x-coordinate of the point into the equation and if the value is equal to the y-coordinate of the point then it is a solution.
(a) (- 1, 3)
y = (- 2 × - 1) + 4 = 2 + 4 = 6 ≠ 3 ⇒(-1, 3) is not a solution
(b) (- 2, 8)
y = (- 2 × - 2) + 4 = 4 + 4 = 8 ⇒ (- 2, 8) is a solution
(c) (0, 1)
y = 0 + 4 = 4 ≠ 1 ⇒ (0, 1) is not a solution
(d) (4, 2)
y = (2 × 4) + 4 = 8 + 4 = 12 ≠ 2 ⇒ (4, 2) is not a solution
Answer:
The farmer should plant 14 additional trees, for maximum yield.
Step-by-step explanation:
Given
So, we have:
Required
The additional trees to be planted for maximum yield
The function is:
Open bracket
Rewrite as:
Differentiate
Equate to 0 and solve for x to get the maximum of x
Divide by -4
The farmer should plant 14 additional trees, for maximum yield.
Part 1:
We are going to divide.
18 ÷ 2/5
18/1 * 5/2
90/2
[ 45 pieces ] can be cut.
Part 2:
We are going to divide.
5 1/5 ÷ 1 4/10
26/5 ÷ 14/10
26/5 * 10/14
260/70
3.7
Note that we need FULL pieces so we are going to round down.
3.7 -> 3
Therefore, the answer is [ B.) 3 ]
Best of Luck!
