Which of the following functions best describes this graph?
O A. y = (x+5)(x-4)
O B. y - (x - 3)(x-6)
O c. y = x2 +9x+18
O D. y = x2 - 2x + 4
Answer:
c. y=x2+9x+18
Step-by-step explanation:
If we factor y=x2+9x+18 using the x method, the factors 3 and 6 mutliply to 18 as well as add to 9. that means y=x2+9x+18=(x+3)(x+6). From the graph, we can see that when y=0, it is at the x's -3 and -6. If we set (x+3)and(x+6) equal to zero (for ex. x+3=0), our x's are -3 and -6 which are the same zeros as the graph
The quadratic function that best describe the graph is y = x² + 9x + 18.
Solution of the graphThe solution of the given graph is determined from the intersection of the curve on the horizontal axis.
The two points of intersection of the curve are -6 and - 3.
Quadratic functionThe quadratic function is determined from the solutions of the curve.
x = -6 or x = -3
x + 6 = 0 or x + 3 = 0
(x + 6)(x + 3) = 0
expand the bracket as follows;
x² + 3x + 6x + 18 = 0
x² + 9x + 18 = 0
y = x² + 9x + 18
Thus, the quadratic function that best describe the graph is y = x² + 9x + 18.

find the domain of the graphed function -4-4 x is all real numbers
Domain and range:
The domain of a function is all the values the the input assumes.
The range of a function is given by all the values that the output assumes.
In a graphic:
The domain is given by the x-values, the horizontal axis.
The range is given by the y-values, the vertical axis.
In this question:
x, in the horizontal axis, assumes values between -4 and 2.
The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.
Thus, the domain of the graphed function is: [tex]-4 \leq x \leq 2[/tex], and the correct answer is given by option D.
For more about domain and range of functions, you can check: https://brainly.com/question/21853810?referrer=searchResults
D. [tex]-4 \le x \le 2[/tex]
The procedure of solution consist consist in determine graphically the Domain of the Function shown in the figure. In this case, the Domain is the Set of values of [tex]x[/tex] in Interval notation, which represented in the "horizontal" axis of the Cartesian Plane. Please notice that black points means that given Function includes extreme values.
By visual examination of the function, we conclude that domain of the function is represented by:
[tex]Dom\{f(x)\} = [-4, 2][/tex]
Which is equivalent to the following expression in Inequality notation:
[tex]-4 \le x \le 2[/tex]
Therefore, we conclude that right answer is D.

Jonas went to the store and bought 2 boxes of cereal for $2.79 each, a box of fruit snacks for $1.89, a gallon of milk for $3.19. Sales tax was $1.05. If Jonas pays with a 20-dollar bill, how much change will he receive
Answer:
$8.29
Step-by-step explanation:
2(2.79) + 1.89 + 3.19 = 10.66
10.66 + 1.05 = 11.71
20 - 11.71 = 8.29

Whats the equation for center (-2,8) and radius 9
Answer:
(x + 2)² + (y - 8)² = 81
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 2, 8) and r = 9, thus
(x - (- 2))² + (y - 8)² = 9², that is
(x + 2)² + (y - 8)² = 81
A student group sells 500 raffle tickets for $2 each. At the drawing the top prize will be
a gift certificate for $100. Second prize will be a $50 gift card and there will be five 3rd
prizes, each a $20 gift card. Do you expect to win or lose (on average)? How much?
Answer:
Step-by-step explanation:
if there are 500 tixets and 7 prizes (1 top prize+1 second prize+5 third prize) your chances of wining are 7/500=0.014 or 1.4% chance
with a 1.4% chance of win and a 98.6% chance to loose in average you can expect to loose.
Emma always learned that when you multiply by a power of ten, all you need to do is add a zero. She used that trick to solve the following problems:
345 x 10 = 3,450
4,789 x 100 = 478,900
5.6 x 10 = 5.60
Emma’s sister told her that her “trick” doesn’t work, and that 5.6 x 10 is NOT 5.60.
Which girl is correct? How do you know?
help meee plsss you smart people
Answer:
Her sis is right
Step-by-step explanation:
She is correct because if you multiply a decimal by a power of 10 instead of adding a zero you bring numbers out of the decimal state.
Answer:
Emma's sister is correct
Step-by-step explanation:
When you multiply by a power of ten you are actually just moving the decimal (which in a whole number you don't see) to the right so when it's a whole number yes you just add a zero but in this instance the answer would be 56.

Right triangle ABC is transformed into right triangle A'B'C what is the scale factor of dilation
Answer:
D. 3
Step-by-step explanation:
The scale factor used to transform right triangle ABC into right triangle A'B'C' is the ratio of any corresponding side length of ∆A'B'C' and ∆ABC.
Thus, using the ratio of side length A'B' to side length A'B', we can get the scale factor as follows:
A'B' = 12 - 6 = 6 units
AB = 4 - 2 = 2 units
Scale factor = A'B' : AB = 6 : 2 = 6/2 = 3

Prices for Oranges
Price A
$2.25 for 6
Price B
$1.30 for 4
Price C
$0.97 for 2
Which gives the prices in order, from least to greatest unit rate?
Price B, Price A, Price C
Price C, Price B, Price A
Price C, Price A, Price B
Price B, Price C, Price A
Price A
$2.25 for 6
Price per orange = $2.25 / 6
= $0.375
Price B
$1.30 for 4
Price per orange = $1.30 / 4
= $0.325
Price C
$0.97 for 2
Price per orange = $0.97 / 2
= $0.485
From least to greatest unit rate
Price B , price A, price C

Give your answer as an improper fraction in its simplest form.
Answer:
[tex] - \frac{27}{7} [/tex]
Step-by-step explanation:
We want to get x alone so we need to get rid of the 7 in front of it.
7x=-27
Divide each side by 7
x= -27/7
This can't be simplified anymore so this is your answer.
