Answer:
X= 3 and y=-9
Step-by-step explanation:
let
x+y=-6 be the equation..1
and 4x + y = 3 be the equation..2
now solving the two equations simultaneously using substitution method
- make x the subject in equation 1. thus the equation turns to x=-6-y when you make x the subject
- substitute x= -6-y into equation 2. Thus the equation 2 then becomes 4(-6-y)+y=3
- simplifying it.. -24-4y+y=3 furthermore ,-24-3y =3 .
solving for y in the relation (-24-3y)=3 . group like terms hence the equation changes to -24-3=3y
-27=3y. divide through by 3
as -27/3=3y/3 to obtain
-9=y.
therefore the value for y is -9
put the y value in either of the two equations to obtain x value
substituting it into equation 1
where x+y =-6
put the y value at the position of y to obtain x-9=-6
x=-6+9
x=3
therefore the value for x and y are 3 and -9 respectively.

Answer:
OPTION D
Explanation:
For zeros of the function (y is the function, a function of x) we need y = 0 so that in turn means we need - 9x - 1 = 0 or - 9x = 1 (i.e. add 1 to both sides); now divide by - 9, and x = 1/-9 which is exactly the same as - 1/9 or - (1/9) and this is the only zero of the function.
or
If y = -9x - 1,
When y = 0
0 = -9x - 1
0 + 1 = -9x - 1 + 1
1 = -9x
1/9 = -9x/9
1/9 = -x
1/[9 X (-1)] = -x/-1
- (1/9) = x
When x = 0
y = (-9 X 0) - 1
y = 0 - 1
y = - 1
