So,
(9 - 11) - (2 2/3 +6 1/3)
-2 - 10
-12
The change was of -12.
(The parentheses weren't needed, i just put 'em there)

Step-by-step
Plot the equation. If you wish to solve a polynomial, let y= polynomial and plot the graph. Best set up a table of values first.
Where the graph crosses the x axis there is a solution for x. There are also solutions for other horizontal lines (y values) by looking at intersections of the graph with these lines. This technique works for linear and non linear equations. You can also use graphs to solve 2-variable systems of equations by examining where the graphs intersect one another. The disadvantage is that you may not be able to have sufficient detail for high degrees of accuracy because of the scale of the graph and drawing inaccuracies.
Answer:
There are 66 number of dogs in Miss Mulero's backyard.
Step-by-step explanation:
Let's set up equation for the given information.
Let there are 'd' number of dogs
and 'c' number of cats.
So, we can set up equation as
d+c=124
d=c+8
Let's solve the system of equations for 'd' and 'c'.
Substitute d as c+8 into the first equation then solve for 'c'
c+8+c=124
Combine like terms
2 c+8=124
Subtract both sides 8
2 c = 116
Divide both sides by 2.
c= 58
Plug in c as 58 into d=c+8
d=58+8
d=66
So, there are 66 number of dogs in Miss Mulero's backyard.
