Answer:
[tex]12x\leq 24[/tex]; [tex]x\leq 2[/tex]
Step-by-step explanation:
So you have 12 math problems that each take x amount of minutes, and have 24 minutes to finish them. Remember, you can't exceed the 24 minutes (but you are allowed to equal that time). So:
[tex]12x\leq 24[/tex]
Then you can simplify by dividing both sides by 2:
[tex]x\leq 2[/tex]

Which function best represents this graph?
Answers
Which property is demonstrated by the equation (5 + a) + 3 = (a + 5) + 3?
Answers
Answer:
Communitive Property
Step-by-step explanation:
Commutative property = 2 + 3 = 3 + 2 or 2(3) = 3(2)
Associative Property = (2 x 3) 5 = 2 (3 x 5) or (2 + 3) + 5 = 2 + (3 + 5)
Inverse Property = 2 + (-2) = 0 or (2/1)(½) = 1
Basic Definitions:
Commutative Property - Gives you the ability to switch the order of the numbers in an expression.
Associative Property - Let's you move the parenthesis in an expression but not the numbers.
Inverse - Uses numbers like 0 and 1.
Using these basic definitions and examples, we can summarize that the best answer would be Communitive Property

A store manager and stroke some new trainees that a book is priced at $21 winds up costing a customer $20.63 what does the tax is included which is the sale tax percentage
Answers
Answer:
1.76%
Step-by-step explanation:
Given
Original price of the book = $21
Price after sales percentage = $20.63
Discount = 21-20.63
Discount = $0.37
sale tax percentage = discount/original price × 100%
sale tax percentage = 0.37/21 × 100
sale tax percentage = 37/21
sale tax percentage = 1.76%
Hence the sale tax percentage is 1.76%

If the parent function is fx) = x^3 which transformed function is shown in the graph?
A. g(x) = (x-3)2
B. g(x) = (x+3)^3
C. g(x) = x^3 + 3
D. g(X) = x^3-3
Answers
Answer:
g(x) = (x-3)³ is the transformed function.
Step-by-step explanation:
Horizontal shift:
If f(x) is the parent function.
Then horizontal shift can be expressed as:
, will shift left units.
[tex]y = f(x - c)[/tex], will shift [tex]f(x)[/tex] right c units.
Given the parent function
f(x) = x³
From the graph, it is clear that the transformed function is indicating that the parent function has been horizontally shifted right 3 units.
Therefore, according to the rule, [tex]y = f(x - c)[/tex]:
g(x) = (x-3)³ is the transformed function.
From the graph,
The Red graph indicates the parent function i.e. f(x) = x³ The Blue graph indicates the transformed function i.e. g(x) = (x-3)³It is clear that the blue graph is obtained when the parent function has been horizontally shifted right 3 units.
Therefore, g(x) = (x-3)³ is the transformed function.

Answers
Step-by-step explanation:
General equation: y = 2 + c/(x - 1)

=> (4) = 2 + c/(4 - 1), c = 6.
Hence the equation is y = 2 + 6/(x - 1).
If y=a sin 3x+ b cos 3x and [tex]\frac{d^{2} y }{dx^{2} }[/tex] = ky, then what is the value of k?
Someone pls asnwer, correct answer will be marked as the brainiest. No spam!!
Answers
Step-by-step explanation:
You have to do first and second derivatives :
y = a sin 3x + b cos 3x
dy/dx = 3a cos 3x - 3b sin 3x
d²y/dx² = - 9a sin 3x - 9b cos 3x
Next, you have to compare it :
let d²y/dx² = ky,
-9a sin 3x - 9b cos 3x = k(a sin 3x + b cos 3x)
-9(a sin 3x + b cos 3x) = k(a sin 3x + b cos 3x)
Therefore, k is equals to 9.

4x=100-6
X=94/4
X=23.5
Ads the sum is said to be AT MOST 100 SO WE WILL ROUND DOWN THE NUMBER
So x=23
X+1=24
X+2=25
X+3=26
Sum=23+24+25+26=98
98<100 so answer is correct

The perimeter of a rectangle is 560 feet. Let X represent the width of the rectangle. Write a quadratic function for the area A of the rectangle in terms of its width.
Answers
9514 1404 393
Answer:
A(x) = x(280 -x)
Step-by-step explanation:
The perimeter is given by the formula ...
P = 2(L +W)
Using the given values, we can solve for the length of the rectangle:
560 = 2(L +x)
280 = L +x
280 -x = L
The area is the product of length and width, so the area is ...
A = LW
A(x) = (280 -x)x

1100 students attend Ridgewood Junior High School. 20% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?
Answers
Answer:
20% of 1100 is 220, so two hundred and twenty students brought their lunch to school on Thursday (and every other school day).
Step-by-step explanation:
The day of the week is a distraction. All you need to know is that 20% of 1100 students bring their lunch to school every day. 20% of 1100 is 200 + 20, or 220. So 220 students bring their lunch to school every day.

B. Evaluate [tex]8.4n-3.2p[/tex] when n=2 and p=4.
To find:
The values of the given expression at the given values.
Solution:
A.
We have,
[tex]\dfrac{3}{8}x-4.5[/tex]
Putting x=0.04 in the above expression, we get
[tex]\dfrac{3}{8}(0.04)-4.5[/tex]
[tex]=0.015-4.5[/tex]
[tex]=-4.485[/tex]
Therefore, the value of the expression at x=0.04 is -4.485.
B.
We have,
[tex]8.4n-3.2p[/tex]
Putting n=2 and p=4 in the above expression, we get
[tex]8.4(2)-3.2(4)[/tex]
[tex]=16.8-12.8[/tex]
[tex]=4[/tex]
Therefore, the value of the expression at n=2 and p=4 is 4.

Answers
Answer:
For an equation like:
y = a*x + b
a is the slope, and this is the rate of change of the function.
For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.
Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.
