Step 1: Define
f(x) = -12x - 23
x = 9
Step 2: Evaluate
Substitute: f(9) = -12(9) - 23Multiply: f(9) = -108 - 23Subtract: f(9) = -131The number of parking spots (y) in the local town (x) years from now can be modeled by the equation below. How many spots are being added every year? y=200x+10000
Answer:
200
Step-by-step explanation:
Given that :
Slope intercept equation :
y=200x+10000
The number of spots being added per year is the value of slope in the equation ;
The general form of a slope intercept equation is :
y = mx + c
Where m = slope
Comparing the equation given to the general formula ; m corresponds to 200 ; hence number of spots added per year = 200
Which expression is not equivalent to
3x– 2?
Ox+x-1-1+x
O 2x+ 2+x
O3-r+ 2r-5 + 2x
O 4x- 4-x+2 will mark brainless
Answer:
B: 2x + 2 + x
Step-by-step explanation:
I just had this question and got it right
The solution is, 2x+ 2+x, is the expression which is not equivalent to
3x– 2.
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
given that,
the expression is : 3x– 2
now, we have to find the expression which is not equivalent to 3x– 2.
now, we have, from the given options:
1.) x+x-1-1+x
= 3x - 2 , which is equivalent to 3x– 2.
2.) 2x+ 2+x
= 3x + 2 , which is not equivalent to 3x– 2.
3.) 3-x+ 2x-5 + 2x
= 3x - 2, which is equivalent to 3x– 2.
4.) 4x- 4-x+2
= 3x - 2, which is equivalent to 3x– 2.
Hence, The solution is, 2x+ 2+x, is the expression which is not equivalent to 3x– 2.

Today, everything at a store is on sale. The store offers a 20% discount.
c. The discounted price of a hat is $18. What is the regular price?
(*Hint* What is your 100%?)
Answer:
14.40
Step-by-step explanation:
20%=0.20
20% of 18 is 18(0.2)=$3.6
$18-$3.6= $14.4
the discount price is $14.4
18 divide by 4 is what you would need to re add so I think it is 24

In the following figure, find the value of x
Answer:
18
Step-by-step explanation:
All the angles added up will equal 180 degrees (recall a straight line has an angle of 180 degrees).
Therefore, you can create the following equation and solve for x:
[tex]2x+3x+2x+3x=180\\10x=180\\x=\frac{180}{10}\\x=18[/tex]
Answer:
x=18
Step-by-step explanation:
equation: 90=2x+3x

1. (-7) + (+2)
2. (-11) + (+6)
3. (-9) - (-4)
4. (-8) - (+3)
Answer:
4. (-8) - (+3)
Step-by-step explanation:
This answer does not result in an answer of -5
This subtracts -3 from -8, which gives you the answer of -11.
So, this answer is correct because it is the one that doesn't result in -5.
Answer:
Problem #4
Step-by-step explanation:
Some things to remember when doing problems like are
Double negative = positive
Double positive = positive
Negative & positive = negative
1. (-7) + (+2) 2. (-11) + (+6) 3. (-9) - (-4) 4. (-8) - (+3)
-7 + 2 -11 + 6 -9 + 4 -8 - 3

Please helpz Your friend evaluates (12 + x) ÷ 6 for x = 6 and gets 13. Explain your friend's error.
Answer:
See explanation
Step-by-step explanation:
The correct answer is obviously 3 because if we substitute x = 6 into the expression we get ( 12 + 6 ) / 6. Using the order of operations, we get 18 / 6 = 3.
The friend likely didn't use the order of operations when evaluating. It's most likely that he substituted x = 6 into the expression and got ( 12 + 6 ) / 6. Instead of first adding 12 and 6, he divided 6 by 6 first to get 1, then added 12 to get 13.

Write an expression for the sequence in
each table.
4.
Position
1 2 3 4 5 1
Value of Term 9
10 11 12 13
Answer:
[tex]a_n=n+9[/tex][tex]a_9=18[/tex]Step-by-step explanation:
Determining the expression for the sequence:
Given the sequence
10, 11, 12, 13
Here, the first element is:
a₁ = 10
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]11-10=1,\:\quad \:12-11=1,\:\quad \:13-12=1[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=1[/tex]
now substituting d = 1 and a₁ = 10 in the nth term
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=\left(n-1\right)+10[/tex]
[tex]a_n=n+9[/tex]
Determining the value of the 9th term
Given the nth term
[tex]a_n=n+9[/tex]
substituting n = 9 to determine the 9th term
[tex]a_9=9+9[/tex]
[tex]a_9=18[/tex]
Therefore, the vale of the 9th term is:
[tex]a_9=18[/tex]

8h 39min
+3h 25min
_________
h min
Answer:
12 hours and 4 minutes
Step-by-step explanation:
To solve first convert both terms to minutes. Do this by multiplying the number of hours by 60, then adding the remaining minutes. 8*60=480, then 480+39=519 minutes. Next, convert 3 hours and 25 minutes to 205 minutes. So now we have 519 minutes and 205 minutes, so add those together to get 724 minutes. Finally, convert back to hours to 12 hours and 4 minutes by dividing by 60.

cos(6x-12) = sin(8x-10)
Subtract sin (8x − 10) from both sides of the equation.
cos (6x − 12) − sin (8x − 10) = 0
Answer:
It doesn't exist
Step-by-step explanation:
since :
cos (90° – x) = sin x
cos(x) = sin(pi/2 - x)
then
cos(6x-12) =! sin(8x-10)
since (8x-10) =! (pi/2- 6+12)
then this identity of cos(6x-12) = sin(8x-10) doesn't exist

The expression 8x + 12y represents the sum of Harry's and Lloyd's total wages, where x represents the number of hours Harry worked and y represents the number of hours Lloyd worked. What is another way to write the expression, and what can you conclude from rewriting it in this way?
Answer:
The rewritten is x + 1.5y.
It can be concluded that Lloyd earns $0.5 per hour more than Harry.
Step-by-step explanation:
Given;
8x + 12y
The expression can be rewritten by dividing it through by 8 as follows:
(8 / 8)x + (12 / 8)y = x + 1.5y
Therefore, the expression can be rewritten as x + 1.5y.
Since x represents the number of hours Harry worked and y represents the number of hours Lloyd worked, the new expression implies that Harry earns $1 per hour while and Lloyd earns $1.5 per hour. Therefore, it can be concluded that Lloyd earns $0.5 per hour more than Harry.
