Consider the following table. is the relationship proportional? explain your answer.
x y
-2 -27
1 12
4 57
10 147

Not proportional.

I looked at the following ordered pairs:

(-2,-27)

(1,12)

(4,57)

(10,147)

Please see I have the points correct.

Thank you kindly.

Step-by-step explanation:

To see if it is proportional, we just need to see if the following equality holds:

?

I'm going to put each fraction into my calculator.

which is totally not true so this relationship is not proportional.

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.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
