PLEASE HELP ME!!! Ror what values of k will the relation not be a function S={(2-|k+1|, 4), (-6, 7)}

Step-by-step explanation:

The relation S is note a function when

2 - |k+1| = -6

Because when they are equal we have two points (-6,4) and (-6,7) in S which implies that -6 is related to two different values.

Now solving

2 - |k+1| = 6

2 - |k+1| = 6

2 - 6 = |k+1|

-4 = |k +1|

But absolute value always non negative, so there is no such k.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
