Find all real zeros of the function y=-9x-1

Mathematics
1 answer:
leonid [27]3 years ago
4 0

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

Sergio039 [100]

Answer:

E=x

or 110= x ( opposite angles of parallelogram are congurent)

E+D = 180 ( angles on st line)

110+D =180

D=70

D=F ( opposite angles of parallelogram are congurent)

so F=70
