in the 2014 mayoral election in a certain city 32000 votes were cast in the 2018 mayoral election for the same city 28800 votes were cast what is the percent decrease in the number of votes cast from 2014 to 2018

10%

Step-by-step explanation:

The first step is to calculate the decrease

= 32,000-28,800

= 3200

Percentage decrease= 3200/32000 × 100

= 0.1 × 100

= 10%

Hence the percentage decrease is 10%

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
