Lady bird [3.3K]

Answer:

<h2>Andy = £ 60</h2><h2>Phobe=£ 180</h2><h2>Polly= £ 30</h2>

Step-by-step explanation:

Let ,

Andy gets £ X

Phone gets 3x

Polly gets y = X/2

Andy gets 2y

2y = X

Now,

$x + 3x + \frac{x}{2} = 270 \\ \frac{x \times 2 + 3x \times 2 + x}{2} = 270 \\ \frac{2x + 6x + x}{2} = 270 \\ \frac{9x}{2} = 270 \\ 9x = 270 \times 2 \: ( \: cross \: multiplication) \\ 9x = 540 \\ x = \frac{540}{9} \\ x = 60$

Replacing values,

$phobe \: gets = 3x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 \times 60 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 180$

$polly \: gets = \frac{x}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{60}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 30$

Hope this helps...

Good luck on your assignment..

Chose the equation for a line that passes through (2,-3) and has a slope of m=-4 in point slope form.

Sladkaya [172]

Answer:

y + 3 = - 4(x - 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 4 and (a, b) = (2, - 3), thus

y - (- 3) = - 4(x - 2), that is

y + 3 = - 4(x - 2)

During summer vacation, you charge people $8 per hour for babysitting and $10 for going to their house. If you make $50 one day,

ioda

Answer: You spent 5 hours babysitting.

Step-by-step explanation:

This situation can be represented by the equation y = 8x+ 10 where y is the money you earn and x is the number of hours.

So if y is equation to fifty dollars then what is x ?

50 = 8x +10 subtract 10 from both sides.

-10 -10

40 = 8x

x = 5

( -3, 6 ) and ( 2, 6 )

Step-by-step explanation:

So your X axis is ( -3, 2).

And your Y axis is ( 6, 6 ).

So from -3 to 2, you going up +5, and from 6 to 6, you not moving anywhere, which means 0.

So the slope is 5/0
