Question

.A relation between x and y if the points (x,y), (3,-5) and (6,0) are collinear. A.3x+5y+30=0. B. 5x+3y-30=0. C. 5x+3y+30=0​

Answer 1

Answer:

the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.

change in direction of propagation of any wave as a result of its travelling at different speeds at different points along the wave front.

measurement of the focusing characteristics of an eye or eyes.

Answer 2

$\Large\mathtt\green{ }\huge\underline\mathtt\red{Answer : }$

5x + 3y = 9 ---(I)

2x - 3y = 12 --- (II)

Add (I) and (II)

7x = 21

x = 3

Putting the value of x = 3 in (I) we get

5(3)+3y=9⇒15+3y=9⇒3y=9-15=-6⇒y=-2

Thus, (x, y) = (3, -6).
