Find the rate of change between (-3,6) (0,-3)

marin [14]

<h3>The rate of change between (-3,6) (0,-3) is -3</h3>

Solution:

Given that,

We have to find the rate of change between (-3,6) (0,-3)

The rate of change is given as:

$Rate\ of\ change = \frac{y_2-y_1}{x_2-x_1}$

From given,

$(x_1, y_1) = (-3, 6)\\\\(x_2, y_2) = (0, -3)$

Substituting the values we get,

$Rate\ of\ change = \frac{-3-6}{0+3}\\\\Rate\ of\ change = \frac{-9}{3}\\\\Rate\ of\ change = -3$

Thus rate of change is -3

The value of a car depreciates by 35% per year. Work out the current value of a car bought 2 years ago for £20000

Rzqust [24]

First year: the depreciation is (35/100) x 20000 = £7000; now the value of the car is £20000 - £7000 = £13000;

Second year: the depreciation is (35/100) x 13000 = £4550; the current value of the car is £13000 - £4550 = £8450.
