Answer: 24 video games
Step-by-step explanation: jasmine has 1,128 bucks originally. she gets some megadeth and metallica cd's (cause if she's got taste, that's probably what she got) and that adds up to 72 bucks. now she wants to buy a whole bunch of video games, which cost 43 each (imagine she got fortnite mod's. ew) so we put that in an equation-
$1,128 - $72 = $1,056
$1,056 divided by 43 equals 24.55813953488372.
when dealing with money, you always round down, so the total number of games she bought was 24

1. A local pizzeria sold 65 pizzas yesterday.
(a) The owner offers the employees a bonus if the number of pizzas sold increases by 20% today. How many pizzas must the pizzeria sell for employees to receive the bonus? Explain your reasoning.
(b) Suppose the actual number of pizzas sold today was 60. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth. Show your work.
Answers
(65 - 60) / 65 = 5/65 = 0.0769 x 100 = 7.69 rounds to 7.7 % decrease compared to the 65 pizza's sold yesterday
Answer: 1) Pizzeria must sell 78 pizzas for receiving the bonus.
2) The number of pizzas sold is decreased by Approximately 7.69 %.
Step-by-step explanation:
1) The number of pizza sold yesterday = 65,
The target for receiving the bonus = 20% more than the number of pizza sold yesterday
= 20% more than 65,
= 65 + 20% of 65 ( 1% = 0.01 ⇒ 20% = 0.2 )
= 65 + 0.2 × 65
= 65 + 13 = 78.
Hence, they must sell 78 pizzas for receiving the bonus.
2) If the actual number of pizza sold today = 60
⇒ Total reduction in the number of pizza = 65 - 60
= 5
Thus, the percentage decrease in the number of pizza
[tex]=\frac{\text{Total reduction}}{\text{The number of pizza sold yesterday}}\times 100[/tex]
[tex]=\frac{5}{65}\times 100[/tex]
[tex]=\frac{500}{65}=7.69230769\approx 7.69\%[/tex]

B.an = 3 * an - 1
C.an = 9 + an - 1
D.an = 3 + an - 1
Answers
The recursive formula that represents the same geometric sequence as [tex]\( a_n = 3 \times 3^{n-1} \)[/tex] is option B: [tex]\( a_n = 3 \times a_{n-1} \).[/tex]
To find the recursive formula that represents the same geometric sequence as [tex]\( a_n = 3 \times 3^{n-1} \)[/tex], we need to find a recursive formula that generates the same sequence.
The formula [tex]\( a_n = 3 \times 3^{n-1} \)[/tex] can be rewritten as:
[tex]\[ a_n = 3 \times 3^{n-1} = 3 \times 3^n \times 3^{-1} = 3 \times \left(3 \times 3^{n-1}\right) \][/tex]
This indicates that each term is 3 times the previous term. So, the recursive formula should involve multiplying the previous term by 3.
Let's examine the options:
A. [tex]\( a_n = 9 \times a_{n-1} \)[/tex] - This represents multiplying the previous term by 9, not 3.
B. [tex]\( a_n = 3 \times a_{n-1} \)[/tex] - This represents multiplying the previous term by 3, which matches the original sequence.
C. [tex]\( a_n = 9 + a_{n-1} \)[/tex] - This represents adding 9 to the previous term, not multiplying it.
D. [tex]\( a_n = 3 + a_{n-1} \)[/tex] - This represents adding 3 to the previous term, not multiplying it.
Therefore, the recursive formula that represents the same geometric sequence as [tex]\( a_n = 3 \times 3^{n-1} \)[/tex] is option B: [tex]\( a_n = 3 \times a_{n-1} \).[/tex]

Which of the following is something that will not affect your homeowners insurance premium? a. the distance of the home from a school b. the distance of the home from a flood plain c. the distance of the home from a fire station d. the distance of the home from a fire hydrant
Answers
Answer:
a. the distance of the home from a school
Step-by-step explanation:
The distance your home is from a flood plain can potentially increase your homeowner's insurance. If your house is close to a flood plain, your insurance will increase.
The distance your home is from a fire station or a fire hydrant either one can lower your insurance. If your home is within so many feet of a hydrant, you get a discount on your insurance; if it is close enough to a fire station, you get a discount as well.
Since the distance a home is from a school has no bearing on the cost of repairing or replacing the home, this will not affect your homeowner's insurance.
Christian is rewriting an expression of the form y = ax2 + bx + c in the form y = a(x – h)2 + k. Which of the following must be true?
h and k cannot both equal zero
k and c have the same value
the value of a remains the same
h is equal to one half –b
Answers
"k and c have the same value" -- k and c do not have the same value. "k" is the y-value of the vertex and c is the constant in your quadratic equation, and the constant is not necessarily the y-value.
"the value of a remains the same" -- this is true. the a's in your equations are the same values, because the a-value is the coefficient of the x-variable in both equations. y = a(x - h)^2 and y = ax^2 -- both of these have a applying to your x-variables.
"h is equal to one half -b" -- this isn't true. the formula for calculating the x value of the vertex (h is the x-value of the vertex) is h = (-b/2a). -b/2a is not the same as one half -b because this answer choice doesn't involve the a-value.
Quadratic equations can be expressed in standard form or in vertex form.
The true statement about [tex]\mathbf{y = ax^2 + bx + c}[/tex] and [tex]\mathbf{y = a(x - h)^2 + k}[/tex] is that: the value of a remains the same
The original expression is given as:
[tex]\mathbf{y = ax^2 + bx + c}[/tex]
He wants to rewrite it as:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
Expand the above equation
[tex]\mathbf{y = a(x - h)(x - h) + k}[/tex]
Open brackets
[tex]\mathbf{y = a(x^2 - hx - hx + h^2) + k}[/tex]
[tex]\mathbf{y = a(x^2 - 2hx + h^2) + k}[/tex]
Remove bracket
[tex]\mathbf{y = ax^2 - 2ahx + ah^2 + k}[/tex]
Compare the above equation to: [tex]\mathbf{y = ax^2 + bx + c}[/tex]
[tex]\mathbf{ax^2 = ax^2}[/tex]
[tex]\mathbf{-2ahx = bx}[/tex]
[tex]\mathbf{ah^2 + k = c}[/tex]
Analyzing the above equations
[tex]\mathbf{ax^2 = ax^2}[/tex]
Divide both sides by [tex]\mathbf{x^2}[/tex]
[tex]\mathbf{a = a}[/tex]
The above equation means that, the value of a remains unchanged.
Hence, option (c) is true

−5x > −22 and −7 ≥ −3
−5x − 7 < −22 and −5x − 7 ≤ −3
Answers
______________________________________________
Explanation:
___________________________
We are the given the following compound inequality:
__________________
" −22 > −5x − 7 ≥ −3 "
__________________________
Consider Answer choice: [A]: −5x − 7 < −22 and −5x − 7 ≥ −3
____________________________________________
Do both of these given in "Answer choice [A]" hold true?
______________________________________
First, does: −5x − 7 < −22 hold true?
___________________________________
Yes, because, in the compound inequality given:
___________________________________
−22 > −5x − 7 ; which is another way of saying that:
__________________
−5x − 7 < −22 .
____________________
Second does: "−5x − 7 ≥ −3 " , hold true?
_____________________________
Yes, because, in the compound equality given,
________________
−5x − 7 ≥ −3 ; which explicitly tells us that it holds true.
_________________
Thus, "Answer choice: [A]: −5x − 7 < −22 and −5x − 7 ≥ −3 " is a correct answer.
___________________
There could be other correct answers, so let us examine the other answer choices:
____________________
Consider "Answer choice: [B]: −5x − 7 > −22 and −5x − 7 ≥ −3 ;
__________________________
Do EACH of these hold true in "Answer choice "B"?
_______________
First let's examine:
_________________
−5x − 7 > −22 ; Does this hold true?
_____________________
No! Because in the compound inequality given,
−5x − 7 < −22 ; so we already know that "Answer choice: [B]" is incorrect; and thus, it makes no difference whether the other part of "answer choice [B]" is correct or incorrect.
_______________________
Let us consider: "Answer choice: [C]: 5x > −22 and −7 ≥ −3" .
Do these hold true with respect to our given compound inequality?
____________________________________________________
No; since NEITHER one of of this 2 (two) components given are are part of our compound inequality given.
__________________________________________________
Furthermore, the particular component given: " −7 ≥ −3" does not make sense. "Negative 7" is not 'greater than or equal to' "Negative 3". -7 ≠ -3 . Additionally, "-7" is LESS THAN—not GREATER THAN—"-3".
_________________________________________________
Also, "−5x > −22" is NOT part of the compound inequality given. So, "Answer Choice: [C]: −5x > −22 and −7 ≥ −3" ; is INCORRECT.
___________________________________________________
Additional note: " −5x < −22" is NOT part of the compound inequality given, either.
____________________
The [incorrect] "Answer Choice: [C]: "−5x > −22 and −7 ≥ −3" ; can be somewhat deceptive.
The compound inequality given:
___________________________
" −22 > −5x − 7 ≥ −3 " ; should be viewed as:
_______________________________________
" −22 > (−5x − 7) ≥ −3 " ;
_____________________________________
and the term, "(−5x − 7)" should be treated as one separate term—just like the terms: "(-22)", and "(-3)".
_______________________________________________
Let us consider "Answer choice: [D]: −5x − 7 < −22 and −5x − 7 ≤ −3 " .
_______________________________________________
Start with: −5x − 7 < −22 . Does this hold true for our original compound inequality?
________________
Yes! (Since in our original compound inequality; "−22 > −5x − 7" ;
and this component of 'Answer choice: [D]' — "−5x − 7 < −22 "— is another way of saying that: "−22 > −5x − 7" (as denoted in our original compound inequality).
___________________
Now, we shall examine the second component of
'Answer choice: [D]' — "−5x − 7 ≤ −3 ".
_____________________
Does this hold true for our original compound inequality?
_______________________
No! This second component given in our 'Answer choice'—is:
"-5x − 7 ≤ −3" ; and in our original compound inequality:
_______________
"−5x − 7 ≥ −3 " !
________________________
As such, since one of the compounds in 'Answer choice: [D]' is incorrect;
_______________________________________________
Answer choice: [D]: "−5x − 7 < −22 and −5x − 7 ≤ −3" ; is incorrect.

What is the equation for this slope question??
4.)The line whose slope is half as great as Its y-intercept. Their sum is 1.
Answers
We are given that the slope is half the y-intercept and their sum is 1. Using these conditions we can solve for b and m (which represent y-intercept and slope) and we find that b=2/3 and m=1/3. Therefore, the equation of the line is y = 1/3x + 2/3.
Explanation:The question is about finding the equation of a line from given conditions. We know that the equation of a line is typically written in the form y = mx + b, where m is the slope and b is the y-intercept. We are given two conditions: the slope is half the y-intercept, and their sum is 1.
Let's assume that the y-intercept is b and the slope is m. Now we can substitute the value of m from the first equation into the second. This gives us: b + b/2 = 1. Solving this, we get b = 2/3 and therefore, m = 1/3.
So, the equation of the line is y = 1/3x + 2/3.
