<span>2x – 6y = 9
Slope is coefficient near x in y=kx+l
</span>2x – 9 = 6y
1/3 x – 3/2 = y
k = 1/3

Let's make our equation in the form of y = mx + b

<span> 2x – 6y = 9

Add 6y on both sides

2x = 6y + 9

Subtract 9 on both sides

6y = 2x - 9

Divide 6 on both sides

y = 1/3 - 3/2

Now, we have it in the form of y = mx + b

In y = mx + b, m is the slope and b is the y-intercept

That means in y = 1/3 - 3/2, the slope is A) 1/3.

Your answer is A) 1/3</span>

notice, Papa Bear is 18inches in diameter, but radius is half that

•Mr. Jones and Mr. Thomas

mamaluj [8]

The profit should be shared in proportion to Mr Jones, Mr Thomas and Mr forson capitals in the ratio 21 : 32 : 27 respectively.

<h3>Proportion</h3>

Mr Jones capital = $12600
Mr Thomas capital =$19200
Mr forson capital = $16200

Total capital = $12600 + $19200 + $16200

= $48,000

Mr Jones proportion = $12600 / $48,000

= 21/80

Mr Thomas proportion = $19200 / $48,000

= 32/80

Mr forson proportion = $16200 / $48000

= 27/80

A hairdryer transfers 36,000J in one minute, what is the power rating of the hairdryer?

Verdich [7]

Answer:

1. 600 watts

2. 35640 J

3. 55%

4. 20 J

5. The cost of running the fire is 8p.

Step-by-step explanation:

1. Energy = 36 000 J , t = 1 minute = 60 seconds

Power = $\frac{energy}{time}$

= $\frac{36000}{60}$

= 600 watts

2. Power = $\frac{work done}{time}$

⇒ work done = Power × time

= 99 × 360

= 35640 J

3. Efficiency = (Output / Input) × 100

= $\frac{55}{100}$ × 100

= 55%

4. Work done = Force × distance

= 5 × 4

= 20 J

5. Given that 1 KWh cost 2p, Power = 4 KW and time = 4 hours.

Power = $\frac{energy}{time}$

Energy = Power × time

= 4 × 4

= 16 KWh

The cost of running the fire = $\frac{16}{2}$

= 8p

Use KMF (Keep multiply flip)
keep the first fraction as it is
change sign to multiplication
flip numerator and denominator of last fraction
then finish
