7x + 9 = 58 i need all the steps
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.

10. An arithmetic sequence has this recursive formula. What is the explicit formula?
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]

Your welcome.
y=3x+14
2x-3y=-14
Substitution method
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.
A health club charges a $50 initial fee plus $2 for each visit. Moselle has spent a total of $144 at the health club this year . Use an equation to find how many visits she has made
Answer:
Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y-intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.
Subtract 50 from both sides-
144-50=2x+50-50
94=2x
Divide 2 from both sides-
94/2=2/2
x=47
Moselle made 47 visits to the health club.

Answer:
A: 12 4/9
Step-by-step explanation:
1/4x (2x + 1) = 29 (Combine like terms, NOT distributive property!!!)
2 1/4x + 1 = 29
- 1 - 1
2 1/4 / 2 1/4x = 28 / 2 1/4
