The point (-3,11) is a solution to : y > = x - 2, 2x + y < = 5
Answer:
621 / 629
Step-by-step explanation:
We are given the following information -
cos x =
, and sin y = 
Respectively we can use the following information -
sin( x + y ) = sin x ( cos y ) + sin y ( cos x ),

Knowing that cos^2x + sin^2x = 1, cos^2y + sin^2y = 1, we can calculate the value of sin x and cos y, plugging it into the first bit " sin( x + y ) = sin x ( cos y ) + sin y ( cos x ) "

Respectively cos y should be 35 / 37 -

Thus,
sin( x + y ) = ( 15 / 17 ) * ( 35 / 37 ) + ( 12 / 37 ) * ( 8 / 17 ),
sin( x + y ) = 621 / 629

1) let molly be y
And let Nancy be x
Since molly is twice as Nancy
So equation is 2x=y
(Twice Nancy age is equal to Molly’s age)
2)let molly be y
Let zanders age be z
Since zander is 6 yrs younger than molly
So 6yrs added to zanders age equals Molly’s age
Eq: z+6=y
3) ) molly’S age =y,Nancy age =x
Since molly is twice as Nancy
So 2x=y. (Nancy is 10 .....given )
2*10 = 20
Or
molly =y
zanders =z
Since zander is 6 yrs younger than molly
Eq: z+6=y ( zandra is 14 ...given )
14+6=20
If u wanna submit it to your teacher the do write in the exact same way as above
Plz mark me brainest:)
