6/11 is the simplest form of the fraction.
First you divide the top and bottom by two 84/2 and 144/2
Next you get 42/77
Finally you see that both are factorable by 7 so you divde 42 and 77 by 7 to get 7/11
Answer:
9
Step-by-step explanation:
we know by definition that

so now we evaluate

and if we want to do an extra step

which works.
Answer:
x = -4
Step-by-step explanation:
f(x) = x² - 16
This is the difference of squares
which factors as
f(x) = (x - 4)(x + 4)
Therefor the negative zero is
x = -4
Number two is proportional just do Y over X y/x meaning divided all the y’s over the x’s so 25 divided by 5 30 divided by 6 35/7 40/8 they all equal 5 so it’s proportional
number three isn’t proportional when you do y/x they all come out differently so you do y2-y1 over x2-x1 16-4/4-2 16-4=12 4-2=2 then you divided 12/2 that equals 6 you do that again but with the next numbers but they don’t equal so it’s no equation no constant
