Answer:
Equation, 45 p + 25 q = 900
Explanation:
Pecan trees yield 45 pounds per acre and hazelnut trees yield 25 pounds per acre.
Pecan tree yield per acre = 45 pounds
Hazelnut tree yield per acre = 25 pounds
Acres of pecan trees in Jenna's farm = p
Acres of hazelnut trees in Jenna's farm = q
Total pounds of nut yielded = 900
So we have the equation,
45 p + 25 q = 900
Two of the given points have the same y-value. The midpoint of those two will be on the line of symmetry, as is the vertex. The x-value there is (-1+5)/2 = 2.
