Answer:

Step-by-step explanation:

y - y_{1} = m( x - x_{1} ) point - slope form of linear equation ;

y = mx + b slope-intercept form of linear equation, (0, b) are coordinates of y-intercept ;

<em>(b).</em> y - 3 = - 7(x - 8)

<u><em>y = - 7x + 59</em></u>

<em>(c).</em> y - (- 2) = \frac{4}{3} [ x - ( - 7)] ⇔ y + 2 = \frac{4}{3} ( x + 7)

<u><em>y = </em></u>\frac{4}{3}<u><em> x + </em></u>\frac{22}{3}<u><em> </em></u>

<em>(d).</em> <u><em>y = - </em></u>\frac{7}{8}<u><em> x + 9</em></u>

Hanadi buys a dishwasher for £240 she wants to put a tag with a price on the dishwashee so that in the sale she can give a disco
Elanso [62]

Answer:

Step-by-step explanation:

Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is

240 + 25/100 × 240 = 240 + 60 = 300

To determine the price tag of 40% discount and that would still ensure that she makes £300,

Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as

x - (40/100 × x) = x - 0.4x = 0.6x

So 0.6x = 300

x = 300/0.6 = 500

So the price tag will be £500
