Answer:
Yes.
Step-by-step explanation:
Yes, because we can replace x^3 by another variable, say y:
x^9 - 5x^3 + 6 = 0
Let x^3 = y, then we have x^9 = (x^3)^2 = y^2:
y^2 - 5y + 6 = 0 which is quadratic from.
Answer:
B I think
Step-by-step explanation:
I think it's B because in b it says so on which means his raise keeps going up each year
Answer: Smoothing constant
Step-by-step explanation:
Y=f(X)
At y-intercept, X=0
f(X)= 0^3-18(0)^3+107(0)-210
= -210
Answer:
The table that has a consistent proportionality between Y and X of 2 is choice 2.
Step-by-step explanation:
Because the proportionality between X and Y is 2, that means for each x value, the corresponding y value will be twice as big. The only option that meets this requirement is choice 2, so that is the correct answer.
