The line passes through the point -4, -8 and has a slope of 3/2 Rewrite an equation in a X plus BY equals C

amid [387]

Answer:

Step-by-step explanation:

(-4,-8)...x = -4 and y = -8

slope = 3/2

in y = mx + b form, the m is ur slope

now sub ur info into y = mx + b......we need to find b, the y intercept

y = mx + b

-8 = 3/2(-4) + b

-8 = -6 + b

-8 + 6 = b

-2 = b

so ur equation is : y = 3/2x - 2.....but u need it in another form

y = 3/2x - 2.....subtract 3/2x from both sides

-3/2x + y = -2 ....then u can multiply by -2 and get 3x - 2y = 4....just in case u dont want fractions

Peter and angad win some money and share it in the ratio 4:1 Peter gets £28 how much did they win in total

Ivanshal [37]

Answer

Find out the how much did they win in total .

To prove

As given

Peter and angad win some money and share it in the ratio 4:1 .

Peter gets £28 .

Let us assume that x be the scalar multiple of the Peter and angad wins money.

Than

Peters money = 4x

Angad money = x

Than the equation

4x = 28

$x = \frac{28}{4}$

x = 7

Thus

Angad money = x

= £7

The total money peter and angad wins = Peters wins + angad win

= £28 + £7

= £35

Therefore the total cost of the peter and angad wins be £35.
