Mathematics

Parabolas can shift up and down or left to right
Parabolas shifting left and right uses the formula of y=(x-a)^2 where a determined the amount it shifts.
E.g. y=(x-3)^2 moves right three units but if it was a +3 instead of -3, it moves three units to the left.
When parabolas move up or down, it uses y=mx^2+b (where b determines the amount it shifts)
If it is +10 , it moves ten units above but if it is -10 it moves ten units down

Find the number set which satisfies each of the problems. If 20 is added to the number, the absolute value of the result is 6.
victus00 [196]

Answer: {-14,-26}

Step-by-step explanation:

Let x be the number.

Given statements:  If 20 is added to the number, the absolute value of the result is 6.

i.e. |x+20| =6

Since |y|=c \Rightarrow y= c \text{ or } y = -c

So, |x+20| =6\Rightarrow\ x+20=6\text{ or }x+20=-6

\Rightarrow\ x= 6-20\text{ or } x= -6-20\\\\\Rightarrow\ x=-14\text{ or } x=-26

hence, set of values of x = {-14,-26}
