Y=2x^2+7x what are the x-intercepts of this graph?

y=2x^2+7x

factor out an x

y = x(2x+7)

using the zero product property

0 = x   0 = 2x+7

x = 0        -7 = 2x

                -7/2 =x

The x intercepts are 0 , -7/2

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.
