2z^4-10z^3+4z^2 factorable?

charle [14.2K]

Yes
factor out the 2z^2 in each term
(2z^2)(z^2-5z+4)
factor some more
z^2-5z+4
find what 2 numbers multiply to get 4 and add to get -5
the numbers are -1 and -4
(z-1)(z-4)

the factored form is
(2z^2)(z-1)(z-4)

The equation y=7.6x represents a proportional relationship what is the constant of proportionality?

prisoha [69]

Answer:

Option B. 7.6

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

where

k is the constant of proportionality

The slope of the linear equation is the same that the constant of proportionality

In this problem we have

$y=7.6x$

the slope is $m=7.6$

therefore

The constant of proportionality k is $k=7.6$
