10. An arithmetic sequence has this recursive formula. What is the explicit formula?
Answers
Answer:
[tex]a_{n}=45-3n[/tex]
Step-by-step explanation:
Method 1:
Arithmetic sequence is in the form
[tex]a_{n} =a_{1} +(n-1)d\\[/tex]
d is the common difference, can be found by:
[tex]d=a_{n}-a_{n-1}=-3[/tex]
Subtituting the [tex]a_{1}[/tex] and [tex]d[/tex]
You get:
[tex]a_{n}=42+(-3)(n-1)=45-3n[/tex]
Method 2 (Mathematical induction):
Assume it is in form [tex]a_{n}=45-3n[/tex]
Base step: [tex]a_{1} =45-3(1)=42[/tex]
Inducive hypophesis: [tex]a_{n}=45-3n[/tex]
GIven: [tex]a_{n+1} =a_{n}-3[/tex]
[tex]a_{n+1}=45-3n-3=45-3(n+1)[/tex]
Proved by mathematical induction
[tex]a_{n}=45-3n[/tex]

7x + 9 = 58 i need all the steps
Answers
Answer:
Step-by-step explanation:
7x + 9 = 58
-9 -9 Subtract 9 from both sides
7x = 49
/7 /7 Divide both sides by 7
x = 7 (this is an apporximation)
Answer:
7
Step-by-step explanation:
1st you need to subtract 9 from both sides like this: 7x+9-9=58-9. and you'll get 7x=49. Then, divide by 7 on both sides like this: 7x/7=49/7. and you'll get x=7.

Step-by-step explanation:
8x+78=2x+114
8x-2x=114-78
6x=36
x=36/6=6
<B=2(6)+114
= 126
y=3x+14
2x-3y=-14
Substitution method
Answers
Answer:
x = -8
Step-by-step explanation:
y = 3x + 14
2x - 3y = -14
So, what is the substitution? Y of course, this is because y is equal to 3x + 14.
2x - 3 (3x + 14) = -14
Multiply 3 with the numbers in the parentheses.
2x - 9x + 42 = -14
So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.
-7x + 42 = -14
Then subtract 42 from both sides.
-7x + 42 - 42 = -14 - 42
Simplify
-7x = -56
Divide 7 by both sides.
-7x / 7 = -56 / 7
x = -8
And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.
