So I am looking at the method of elimination but I get a little bit lost why there is a positive +1 underneath the -1 , where does the +1 come from?
Answers
Answer:
it is because its being carried to the other side
Step-by-step explanation:
When you add 1 to negative 1 it becomes 0, so we are trying to make the right hand side equal to the left hand side. If that makes any sense.
When doing this you need to do the inverse operation on BOTH sides of the equation, in this case the equation is
-1 + y = -3
( the inverse operation of subtraction is addition)
So you add 1 to both sides to find out what y equals, -1 + 1 cancels out, -3 + -1 is equal to -2
Therefore the y = -2

Answers
The conclusion that can be drawn from the table is (c) There is not an association between type of pet and food preference because the row relative frequencies are similar for the dog and cat rows
What is conditional relative frequency?A conditional relative frequency is simply a two-way table that shows the relationship between table entries
How to determine the association?The table is given as:
Food preference
Dog 0.47 0.52 0.495
Cats 0.53 0.48 0.505
Total 1 1 1
The entries at rows 1 and 2 i.e. 0.47 and 0.52 & 0.53 and 0.48 are close.
This means that there is no association between them because of the closeness

What is a function?An expression which defines the relationship between two variables (one independent and one dependent variable).
What is dependent and independent variable?The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes with the change of independent variable.
What is inverse of a function?A function that undoes the original function is called the inverse function.
How to find the inverse of y=7x+3 ?To find the inverse function of a given function,
first we will have to interchange the variablesIn the problem,
y is the independent variable x is the dependent variabley=7x+3
To find the inverse
x = 7y + 3 ( interchanging the variables )

If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times Natalie's age, the result is 88. Write and solve a system of equations to find how old Fred and Natalie are.
Answers
Natalie's age = n
Fred's age = f
n + f = 43
4n + f = 88
f = 43 - n
4n + (43 - n) = 88
3n + 43 = 88
3n = 45
n = 15
f = 43 - n
f = 43 - 15
f = 28
Natalie is 15
Fred is 28

3) Alternate exterior angles = congruent
= -1 + 14x
= 12x + 17
4) Corresponding angles = supplementary (measures add up to 180 degrees)
= 23x - 5
= 21x + 5
\\NONSENSE ANSWERS WILL BE REPORTED\\
Answers
3) x = 9, 125 degree
4) x = 5, 110 degree
Step-by-Step Explanation:
In Q3 :-
Alternate Exterior Angles are Equal.
Therefore,
=> -1 + 14x = 12x + 17
= 14x - 12x = 17 + 1
= 2x = 18
=> x = 18/2 = 9
Therefore, x = 9
Now finding each angle :-
=> -1 + 14x
= -1 + 14(9)
= -1 + 126
= 125
=> 12x + 17
= 12(9) + 17
= 108 + 17
= 125
Hence, both are Equal.
In Q4 :-
Corresponding Angles are Equal.
Therefore,
=> 23x - 5 = 21x + 5
= 23x - 21x = 10
= 2x = 10
=> x = 10/2 = 5
Therefore, x = 5
Now finding each angle :-
=> 23x - 5
= 23(5) - 5
= 115 - 5
= 110
=> 21x + 5
= 21(5) + 5
= 105 + 5
= 110
Hence, both are Equal.
