What is the sign of x/y times 7y^3 when x<0 and y>0? A. Positive B. Negative C. Zero

1 answer:

X <0 means x would be negative.

For x/y, a negative divided by a positive would give a negative answer.

A negative multiplied by a positive would result in a negative.

The answer would be B. Negative

3(-5^2)+14(-5)+k=0

75-70+k=0

5+k=0

k=-5

x=-2/75
