Answer:
Step-by-step explanation:
the solution is right
x^2-6x-7=0:
x^2-6x-7=0
(add 7 to both sides)
x^2-6x=7
x^2-6x+9=7+9 (the coefficient of x² will be used to divide all sides)for here its 1, it will remain same ,
then we get the coefficient of x, divide it by 2 and square it and add it to both sides
which is like these
x²-6x=7
the coefficient of x is -6
-6/2 = -3, square it (-3)² = 9
then add 9 to both sides
x^2-6x+9=7+9
simplifiy the squares on the left hand side
x²+9 = (x-3)²
(x-3)^2=16
√(x-3)^2 )=±√16
x-3=± 4
x=-3±4
then simplify each sign
x=-3+4 x=-3-4
x=1 x=-7

Answer:
1st Graph:
Add all the numbers (Do the same to 2nd Graph)
Then add
answer will be shown
I got 4.42 hope this helps:)
The value would be always 1 because....
1) When the numerator and a denominator are the same they would be whole which is 1.
2) For example, 10/10 equals 1
3) Another example, 120/120 equals a whole which is 1 :)
4) Please give this a THANKS and the BRAINIEST ANSWER/CROWN!!!
5) HAVE A GREAT LOVELY DAY!!! :) :D
