Y=x+3 and y=x-y help me ​

Mathematics
1 answer:
Nuetrik [128]3 years ago
4 0

Step-by-step explanation:

Given

y = x + 3.....equation 1

y = x - y

or y + y = x

or 2y = x

or y = x / 2......equation 2

Now

Putting equation 2 in equation 1

x / 2 = x + 3

x - x/2 = - 3

<u>2x</u><u> </u><u> </u><u>-</u><u> </u><u>x </u> = - 3

2

x / 2 = -3

x = - 6

Now

y = x/ 2

= - 6/2

= - 3

Hope this helps

Prove: If a chord of a circle has a common end point with a diameter and makes an angle of 30° with it, prove that the distance
nignag [31]

Step-by-step explanation:

The perpendicular distance between the chord and the center of the circle forms a right triangle with the chord and the radius.  Using trig:

sin 30° = x / (D/2)

sin 30° = 2x / D

1/2 = 2x / D

x = D/4
