According to the Rational Root Theorem, Negative two-fifths is a potential rational root of which function? f(x) = 4x4 â€" 7x2 x 25 f(x) = 9x4 â€" 7x2 x 10 f(x) = 10x4 â€" 7x2 x 9 f(x) = 25x4 â€" 7x2 x 4.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

its 69.420

step-by-step explanation:

uhhh idk u yolo?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
