Answer:
let alpha be x and beta be y
Step-by-step explanation:
x+y= -b/a
x+y=-1/6
and xy= c/a
xy= -1/3
according to question
1/x+1/y -xy =(x+y)/xy-xy
(-1/6)/(-1/3)-(-1/3)
1/2+1/3
the answer is 5/6
Answer:
-21
28
Step-by-step explanation:
1) if r = -4
Substitute r = -4 in 3r - 9
= 3 * (-4) - 9
= -12 - 9
= -21
2) ( 4 / 7 ) * x = 16
4 * x = 16 * 7
x = 4 * 7
x = 28
Answer:
JUSTIFICATION↓
∠1 ≅ ∠2 <u>(∵ Vertically-opposite angles are equal)</u>
Step-by-step explanation:
Since ∠1 lies vertically opposite to ∠2 and vice -versa , therefore ∠1 and ∠2 are equal to each other

Hey there! :)
The formula for (a + b)^2 is a^2 + 2ab + b^2. In this case, x is a, and so b would have to be 4. We would need to add 4^2 = 16 to both sides of the equation to complete the square.
