Step-by-step explanation:
We will prove by mathematical induction that, for every natural
,
We will prove our base case, when n=4, to be true.
Base case:

Inductive hypothesis:
Given a natural
,
Now, we will assume the induction hypothesis and then use this assumption, involving n, to prove the statement for n + 1.
Inductive step:

With this we have proved our statement to be true for n+1.
In conlusion, for every natural
.
The equations y = 3x - 4 and y = 3x + 1 are linear equations
The equations have no solution
<h3>How to determine the solution of the equations?</h3>
The equations are given as:
y = 3x - 4
y = 3x + 1
Next, we plot the graph of the equations y = 3x - 4 and y = 3x + 1
From the graph (see attachment), we can see that the equations do not have a point of intersection
Hence, the equations has no solution

Answer: note I will just replace the Shape by an X
a) X + 9 = 9 + 6; X=6 Commutative Propertie
b) 0 + X = 7; X=7 Additive Identity Propertie
c) X + (7 + 3) = (4 + 7) + 3; X=4 Associative Propertie
Step-by-step explanation:
There are four mathematical properties which involve addition. Commutative, associative, additive identity and distributive properties.
Commutative property: When two numbers are added, the sum is the same regardless of the order of the addends.
Associative Property: When three or more numbers are added, the sum is the same regardless of the grouping of the addends.
Additive Identity Property: The sum of any number and zero is the original number.
Distributive property: The sum of two numbers times a third number is equal to the sum of each addend times the third number.
Answer:
30, 150
A + B = 180
A = 2B+ 90
2B + 90 + B = 180
3B = 90
B=30 A=150
