Answer:
the equation that can be used to determine how many hours Amanda babysitted for the family =
20 + 5x = 35
Amanda babysitted for 3 hours
Step-by-step explanation:
From the question, we know that:
Amanda charges $20 fee for babysitting plus an additional $5 per hour.
Let the number of hours she babysits be represented by x
This is represented by the equation:
$20 + $5× x
= 20 + 5x
We are also told:
The Wilson family paid the babysitter a total of $35 for a night of babysitting.
Hence the equation that can be used to determine how many hours Amanda babysitted for the family =
20 + 5x = 35
5x = 35 - 20
5x = 15
x = 15/5
x = 3 hours
Therefore, Amanda babysitted for 2 hours

A Super Lemon currently weighs 100 kg and is increasing by 4 kg per day. The price for Super Lemon’s
is currently $8.90 per kg but is decreasing at $0.30 per day. The cost to grow the lemon is $0.80 per
day.
Determine how many days from now the lemon should be sold to maximize profit and what the
maximum profit will be.
The lemon should be sold 3 days from now to maximize profit, which would be $894.80.
Profit calculationGiven that a Super Lemon currently weighs 100 kg and is increasing by 4 kg per day, and the price for Super Lemon’s is currently $8.90 per kg but is decreasing at $0.30 per day, and the cost to grow the lemon is $0.80 per day, to determine how many days from now the lemon should be sold to maximize profit and what the maximum profit will be, you should perform the following calculation:
Initial profit = $890(100 + 4x1) x (8.90 - 0.30x1) - (0.80x1) = 893.6(100 + 4x5) x (8.90 - 0.30x5) - (0.80x5) = 884(100 + 4x2) x (8.90 - 0.30x2) - (0.80x2) = 894.8(100 + 4x3) x (8.90 - 0.30x3) - (0.80x3) = 893.6Therefore, the lemon should be sold 3 days from now to maximize profit, which would be $894.80.

([x/(y-1)](-4)-[xy+(-3)]/(-1) if x=-5 and y=-2
The value of expression at x = - 5 and y = - 2 is,
⇒ 1/3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ ([x/(y - 1)](-4) - [xy + (-3)]/ (-1)
Now, We can put x and y in above expression as;
⇒ ([x/(y - 1)](-4) - [xy + (-3)]/ (-1)
⇒ [- 5 / (- 2 - 1) ] (- 4) - [- 5×- 2 + (- 3)] / (- 1)
⇒ [ - 5/- 3 ] (- 4) - [10 - 3] / (- 1)
⇒ - 20/3 + 7
⇒ 1/3
Thus, The value of expression at x = - 5 and y = - 2 is,
⇒ 1/3

The vertex is located at (8.33, 236.67).
What does this point represent in context?
Answer:
The vertex is the maximum of the graph. The y-coordinate of the maximum is 236.67, which means the greatest possible daily profit from the sale of soccer balls is $236.67. This maximum profit occurs when x = 8.33, or when the store charges $8.33 per soccer ball.

Step-by-step explanation:
47 = 2(x + 3) + 3(x - 3)
what's the answer to this ?
[tex]47 = 2(x + 3) + 3(x - 3)[/tex]
[tex]47 = 2x + 6 + 3x + - 9[/tex]
[tex]47 =(2 x + 3x) + (6 + - 9)[/tex]
[tex]47 = 5x + - 3[/tex]
[tex]47 = 5x - 3[/tex]
[tex]5x - 3 = 47[/tex]
[tex]5x = 47 + 3[/tex]
[tex]5x = 50[/tex]
[tex]x = \frac{50}{10} [/tex]
[tex]x = 10[/tex]
Let us check whether or not we have found out the correct value of x by placing 10 in the place of x .
So :-
[tex]47 = 2(10 + 3) + 3(10 - 3)[/tex]
[tex]47 = (20 + 6) + (30 - 9)[/tex]
[tex]47 = 26 + 21[/tex]
[tex]47 = 47[/tex]
LHS = RHSAs the left hand side of the equation is equal to the right hand side of the equation , we have found out the correct value of x .
Therefore , 47 = 2 ( 10 + 3 ) + 3 ( 10 - 3 ) and x = 10 .
Which of the expressions below can be factored using the difference of
squares method?
A. 17x^2+23y^2
B. 25x^2+64y^2
C.25x^2-64y^2
D.17x^2-23y^2
Answer:
C
Step-by-step explanation:
A difference of squares can be factored in general as
a² - b² = (a - b)(a + b)
We are looking for 2 terms separated by a - and perfect squares on either side. The only one meeting this criteria is
25x² - 64y²
= (5x)² - (8y)²
= (5x - 8y)(5x + 8y) ← in factored form

Find the mode of the data set. 11, 19, 16, 12, 19, 16, 11, 12, 16, 13
Answer:
mode is 16
Step-by-step explanation:
because there are 3 16s which is the most common number in this data set
Answer:
16
Step-by-step explanation:
Your mode would be 16
Your mode is 16 because the mode is the number that appears most in the data set and 16 appears 3 times in the data set.
Here is some extra answers just incase.
median=14.5
Because median is the middle number and because 13,16 are the middle numbers then you split that in middle and plus you also have to sort it least to gretest.
Mean=14.5 also because mean is the average of all the numbers in the data set.
range is 8
Range is the highest number subtracting lowest number so 19-11=8
Minimum is 11
The minimum is the lowest number and the data set so 11
maximum is 19
Maximum is the highest number in the data set.
Hope it helps have a great day:)

Answer:
(multiply both sides by 6)
6×[tex]\frac{4h+4}{6}[/tex]-10×6=-2h×6
(simplify)
4h+4-60=-12h
4h-56=-12h
(move constant to the right side and variable to the left)
4h+12h=56
16h=56
(divide both sides by 16)
h=7/2

PLEASE HELP!! What is the equation of the following graph in vertex form?
Answer:
y = (x - 4)² - 4Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - h)² + k
the vertex is (4, -4) ⇒ h = 4, k = -4
so:
f(x) = a(x - 4)² + (-4)
f(x) = a(x - 4)² - 4
So the right answer is the first one.

Anna does sit-ups to get ready for her first triathlon. When she starts, she does a sit-up every 222 seconds. But, as she gets tired, each sit-up takes longer and longer to do. Is the number of sit-ups Anna does proportional to the time she spends doing them? Choose 1 answer: Choose 1 answer: (Choice A) A Yes (Choice B) B No
Answer:
Choice B) No.
Step-by-step explanation:
When she starts , she does a sit-up every 222 seconds.
But as she gets tired, each sit-up takes longer and longer to do.
It means, each sit-up takes more time than she did at beginning.
So, it is NOT proportional to the time.
If it is proportional, she should take constant number of sit-ups even she get tired.
