At the start of 2014, mike's car was worth £12000. the value of the car decreased by 30% every year. what is the value of the car in2017

$4,116.

Step-by-step explanation:

Beginning of 2015:

30% of 12000 = 30/100 x 12000 = 3600

The value in 2015: 12000-3600 = $8400.

The start of 2016:

30% of 8400 = 30/100 x 8400 = 2520

The value in 2016 = 8400-2520 = $5880.

Start of 2017

30% of 5880 = 30/100 x 5880 = 1764

Value in 2017 = 5880-1764 = $4116.

So, the value of his car at the start of 2017 is $4116.

Hope this helped and good luck! (:

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
