Answer:
y = -0.07x2 + 3.07x
Step-by-step explanation:
For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.
So, for 2 plants, we have (3 - 0.07) * 2
For 3 plants, we have (3 - 2*0.07) * 3
For x plants, we have (3 - (x-1)*0.07) * x
So we can model the final result of the amount of beans 'y' with the equation:
y = (3 - (x-1)*0.07) * x
y = (3 - 0.07x + 0.07) * x
y = (3.07 - 0.07x) * x
y = -0.07x2 + 3.07x
(In this equation we have a = -0.07, b = 3.07 and c = 0)

Answer:
3rd
Step-by-step explanation:
The definition of an inverse function is that h(f(x)) = x
Therefore, all we need to do is to plug x + 3 into your option choices to find which one returns x.
Therefore, the third option gives you:
x+3-3 = x
Answer:
x=7
y = 4
Step-by-step explanation:
Since it is a parallelogram
2x-2 =12
and 2y =8
2x-2=12
Add 2 to each side
2x-2+2 =12+2
2x = 14
Divide by 2
2x/2 =14/2
x = 7
2y =8
Divide by 2
2y/2 =8/2
y =4
