I don't think you have the correct options. 9/12 + 6/12 = 15/12. To simplify, you divide each value by 3 and get 5/4, which, as a mixed number, would be 1 1/4, and neither 5/4 or 1 1/4 is an option. I hope this helps!

fractions with different denominators, you must first find equivalent

Hope i helped!
7=apple
2=peaches
12 total
3/9 because there is 3 left that is neither apple nor peach.
Answer:
Step-by-step explanation:
1) we have to solve the associated equation
-16x^2 + 24x + 16 = 0
-2x^2 + 3x + 2 = 0
2x^2 -3x -2 = 0
Δ = 9 + 16 = 25
x1 = (3 + 5)/4= 2
x2 = (3 - 5)/4 =-1/2
the x intercepts are -1/2 and 2
2) a maximum because the parabola opens downwards (the first term is negative)
V(x) = -b/2a = -24/-32 = 3/4
V(y) = -16(9/16) + 24(3/4) + 16 = -9+18 + 16 = 25
V(3/4,25)
3) for draw a parabola is are necessary the coordinates of the vertex and of two points: one that lies to left of the vertex, and one that lies on the right to the vertex.
So we already have the necessary informations to draw it.
