Find the Constant of Proportionality Given a Coordinate. (k=ylx) 1. (3,51) 2. (8,96) 3. (0.5,12.5) 4. (0.625,5.625)​

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

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.

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)
