Answer:

15x^2 - 14x - 8 = 0.

Step-by-step explanation:

(x - 4/3)(x + 2/5) = 0

Converted to integer values by multiplying the first bracket by 3 and the second by 5:

(3x - 4)(5x + 2) = 0

Expanding the brackets:

15x^2 + 6x - 20x - 8 = 0

15x^2 - 14x - 8 = 0.

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 $k=7.6$
