Use slopes and y intercepts to determine if the lines 3x+3y=-1 and -x+4y-4 are parallel or not

Since slopes are not same therefore lines are not parallel

Step-by-step explanation:

slope of 3x+3y=-1 is -1

slope of  -x+4y-4=0 is 1/4

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.
