Answer:

0.19+0.46i and 0.19-0.46i

Step-by-step explanation:

\neq (-b+\sqrt{b^2-4ac} )/2a\\and\\(-b-\sqrt{b^2-4ac} )/2a\\\\a=8\\b=3\\c=2\\(-3+\sqrt{3^2-4*8*2} )/(2*8)\\= - 0.1875+0.463512i\\(-3-\sqrt{3^2-4*8*2} )/(2*8) = -0.1875-0.463512i

hope its right

Solve the following system of equations. With multiplication <br> 4x– 3y = -11<br> - 7x-8y= 6
Aliun [14]

4x - 3y = -11

-7x - 8y = 6

We need to cancel out one of the variables so let's multiply the first equation by 8 and the second by 3 and aim to cancel y.

32x - 24y = -88

-21x - 24y = 18

Now we subtract,

53x = -106

x = -2

3y = 4x + 11 = 4(-2) + 11 = 3

y = 1

Answer: (x,y)=(-2,1)

Check:

4(-2) -3(1) = -8 - 3 = -11, good

-7(-2) - 8(1) = 14 - 8 = 6, good

The coordinate point F(-8, 0) after a dilation with scale factor of 0.25, centered at the origin, becomes the point
FrozenT [24]

Answer:

(-2,\, 0).

Step-by-step explanation:

Dilate a point (x,\, y) by a scale factor of r with (a,\, b) as the center, and the resultant point would be at (a + r\, (x - a),\, b + r\, (y - a)).

In this question:

Point to dilate: (x,\, y) = (-8,\, 0).

Scale factor: r = 0.25.

Center of dilation: (a,\, b) = (0,\, 0).

The resultant point would be:

(0 + 0.25\, (-8 - 0),\, 0 + 0.25\, (0 - 0)), which simplifies to (-2,\, 0).
