Answer:
y = 28x
Step-by-step explanation:
To find the answer, we need to divide the number of bushels by the number of acres. If the quotient is the same for all three divisions, then the quotient is how many times x is multiplied to get y.
140 / 5 = 28
224 / 8 = 28
420 / 15 = 28
Therefore, y = 28x is our answer.
Answer:
If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.
actually this factors by grouping:
f(x)=x³+3x²-x-3
= x²(x+3)-1(x+3)
=(x+3)(x²-1)
=(x+3)(x-1)(x+1) // difference of squares
By zero product property roots are
-3, -1, 1
4d + 9 - d - 8 = (4d - d) + (9 - 8) = d(4 - 1) + 1 = 3d + 1
