30<br> Solve by elimination:<br> 2x - 3y = -6<br> -2x - 2y = 26 ,

Arturiano [62]

Answer:

x=-9,y=-4

Step-by-step explanation:

2x-3y=-6...(1)

-2x-2y=26...(2)

To solve we will have to eliminate one of the given variables, the variable to be eliminated is x

And it can be done by adding up (1) and (2)

It gives

-5y=20

Divide both sides by-5

y=-4

Then substitute the value of y into (1)

2x-3(-4)=-6

2x+12=-6

Substrate 12 from both sides

2x=-18

Divide both sides by 2

x=-9

Therefore x gives -9 and y gives-4

Help me solve this please

Answer:

D'G' = 52.5 units

Step-by-step explanation:

Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5

D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )

G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )

Calculate D'G' using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)

D'G' = $\sqrt{(-28-3.5)^2+(-17.5-24.5)^2}$

= $\sqrt{(-31.5)^2+42^2}$

= $\sqrt{992.25+1764}$

= $\sqrt{2756.25}$

= 52.5 units
