(3/4)x + (5/8) x =4x

.75. .625

.75x +.625x = 4x

1.375x = 4x

subtract 4x from each side because you want to get like terms (x) together.

equation is now
1.375-4x= 0

-2.625x= 0


-2.625× = 0
------------- -----------
-2.625 -2.625

zero can't be divided by anything so

x=0

The rate of change of the relationship is 6/5

<h3>Rate of change of a line</h3>

The rate of change of a line is also known as the slope of the line. The formula for calculating the slope of a line is expressed as:

Slope =y2-y1/x2-x1

Given the coordinate points (-3,-2) and (2, 4). On substituting;

Slope = 4-(-2)/2-(-3)

Slope =4+2/2+3

Slope = 6/5

Hence the rate of change of the relationship is 6/5

kozerog [31]

Answer:

The answer to your question is:    k(-5) = -115

Step-by-step explanation:

Function       k(n) = n³ - 3n      find k(-5)

                    k(-5) = (-5)³ - 3(-5)             substitution

                    k(-5) = -125 + 15                simplify

                    k(-5) = -115
