What is the leading
coefficient of F(x)=-2x^2+5x-4

-2

Step-by-step explanation:

The leading term is -2x^2.  The leading coefficient of that term is -2.

-2

Step-by-step explanation:

The leading coefficient is the number in front of the highest power term

The highest power term is x^2

The number in front is -2

The leading coefficient is -2

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
