Answer:
Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).
Step-by-step explanation:
Misha's group was asked to write an expression equivalent to
7y²z + 3yz² - 3
When Mr. Chen checked their answers, he found only one to be correct.
And she was Helena.
Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).
Because, (7y²z + 6yz²- 5 - 3yz² + 2)
= 7y²z + (6yz² - 3yz²) - (5 - 2)
= 7y²z + 3yz² - 3 (Answer)
This is not an Equation! this is an Sentence in Al Jebra!
but you means : if 3ax+b=c, then x =?
3ax=c-bX =
point slope form means (y-y1)=m(x-x1)
so u need to find the slope gradient from those 2 points
m=y2-y1/x2-x1
=-6-6/11-7
=-12/4
=-3
and finally x1,y1=7,6
(y-y1) =m(x-x1)
(y-6) =-3(x-7)
Answer:
That would be A = 35.093665 m^2 (or depending on what label youre using)
-7 + 3w = 4w - 8
-7 = 4w - 8 - 3w
-7 = w - 8
-7 + 8 = w
1 = w
hope this helped, blessings! :)
