Answer:

X=1

Step-by-step explanation:

5(2x - 8) + 15 = -15

10x - 45 + 15 = -15

John bought a 2-year-old car for £ 12 000. Three years later he decides to sell the car; “I think that the value of the car is i
lions [1.4K]

Answer:

Actual value after 5 years is £1344 more than John's value.

Step-by-step explanation:

Johns estimate:-

V = k/t (inverse proportionality)   where V = value of the car and t = it's age.

When t = 2, V = £12,000:-

12,000 = k/2 giving k = 24,000

Therefore the value at 5 years of age, according to John's proposition is

V = 24,000 / 5  =  £4,800

The actual value using the given depreciation is

12000(1 - 0.2)^3 = £6144

Difference is  £1344

Given the points P(2,-1) and Q(-9,-6), what are the coordinates of the point on directed line segment PQ that partitions PQ in t
gayaneshka [121]

ANSWER

( -  \frac{23}{5} , - 4)

EXPLANATION

Given the points P(2,-1) and Q(-9,-6),the coordinates of the point that partition the directed line segment PQ in the ratio 3:2 is given by

x = \frac{ mx_2+nx_1}{m + n}

y= \frac{ my_2+ny_1}{m + n}

Where m=3 and n=2

x = \frac{ 3 ( - 9)+2(2)}{3+ 2}

x = \frac{  - 23}{5}

y= \frac{ 3( - 6)+2( - 1)}{3 + 2}

y= \frac{  - 20}{5}  =  - 4

The point is

( -  \frac{23}{5} , - 4)
