-4 > 10 – 7x
Solve for x.

x>2

Step-by-step explanation:

First begin with the original equation:

-4> 10-7x

Then, subtract 10 from both sides to isolate x:

-14> -7x

Now, divide by -7 on each side:

2< x

The sign switches because, we divided by a negative. Then, just put the x variable first:

x> 2

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

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.
