Yes, the given equation is quadratic equation.
Here it has been given that,
3x² - 5x + 9 = x² - 7x + 3
Now, after solving above equation further we obtain,
2x² + 2x + 6 = 0
From the above equation the factor 2 is taken out as it is common and now the equation looks like : x² + x + 3 = 0
The coefficients of the quadratic equation are compared and if it meets the criteria then it is quadratic equation otherwise not.
Now as we can see, the above equation clearly represents a quadratic equation of the form ax² + bx + c = 0, where a = 1, b = 1 and c = 3.
Hence, the above given equation is a algebraic quadratic equation.
Which of the following is quadratic equation 3x² - 5x + 9 = x² - 7x + 3 ?

Answer:
h = 12 m
[tex] v_{cylinder}= 235.5 \: {m}^{3} [/tex]
Step-by-step explanation:
Radius of cylinder (r) = 5/2 = 2.5 m
[tex] {h}^{2} = {13}^{2} - {5}^{2} \\ h = \sqrt{ {13}^{2} - {5}^{2} } \\ h = \sqrt{169 - 25} \\ h = \sqrt{144} \\ h = 12 \\ \\ v_{cylinder} = \pi {r}^{2} h \\ v_{cylinder}= 3.14(2.5) ^{2} (12) \\ v_{cylinder}= 235.5 \: {m}^{3} [/tex]

You are doubling the amount of boxes there are each time:
Pattern 1: 1 box
Pattern 2: 2 boxes
Pattern 3: 4 boxes
Pattern 4: 8 boxes
Pattern 5: 16 boxes
Pattern 6: 32 boxes
Pattern 7: 64 boxes.
Each box takes 4 matches to create. There are 64 boxes in total by the 7th pattern. Multiply 4 with 64:
64 x 4 = 256
B) 256 matches is your answer.

A line that includes the point (2,7) has a slope of
–
8. What is its equation in point-slope form?
Use the specified point in your equation. Write your answer using integers, proper fractions, and improper fractions. Simplify all fractions.
Answer:
y - 7 = -8(x-2)
Step-by-step explanation:
The point slope form is: y-y1=m(x-x1)
From the information that was given, we know our two points: (2,7)
From here, we can fill in some of the missing information: y-y1=m(x-x1) → y - 7 = m(x-2)
Now I can't tell if you wrote down -8 or just 8, but just in case my answer isn't the right number.
The answer would either be: y - 7 = -8(x-2) [if you wrote down -8 as the slope]
OR
The answer would be: y - 7 = 8(x-2) [if you wrote down 8 as the slope]

Imagine the center of the Seattle Great Wheel is located at (0, 0) on a coordinate grid and the radius lies on the x-axis. Write an equation of a circle for the Seattle Great Wheel and then sketch an image of your equation on the graph provided or insert your own graph.
Center is 0,0 and diameter is 175
Answer:(x-0)^2 + (y-0)^2=30^2
Step-by-step explanation:
The equation of the circle is x^2 +y^2 = 7656.25
How to determine the equation of the circle?The given parameters are:
Center = (0,0)
Diameter = 175
The equation of a circle is represented as:
(x - a)^2 +(y - b)^2 = r^2
Where
Center = (a,b) = (0,0)
r = radius = 175/2
So, we have:
(x - 0)^2 +(y - 0)^2 = (175/2)^2
Evaluate
x^2 +y^2 = 7656.25
Hence, the equation of the circle is x^2 +y^2 = 7656.25

[tex]D.\ (3,\frac{1}{8})[/tex]
Step-by-step explanation:
Given
[tex]y = (\frac{1}{2})^x[/tex]
Required
Points that lies on the above graph
From the given options, only option D lies on the point and the proof is as follows:
[tex]D.\ (3,\frac{1}{8})[/tex]
This means that:
[tex]x = 3;\ y = \frac{1}{8}[/tex]
Substitute [tex]x = 3;\ y = \frac{1}{8}[/tex] in [tex]y = (\frac{1}{2})^x[/tex]
[tex]\frac{1}{8} = (\frac{1}{2})^3[/tex]
[tex]\frac{1}{8} = \frac{1^3}{2^3}[/tex]
[tex]\frac{1}{8} = \frac{1}{8}[/tex]
See that the values at the right and left hand side of the equation are the same.
This means that, [tex]D.\ (3,\frac{1}{8})[/tex] lies on [tex]y = (\frac{1}{2})^x[/tex]

The function f(x)=(25)x
is shown on the coordinate plane. Which statement is true?
Answer: In the right end, as x increases without bound, the graph of f(x) decreases.
In the left end, as x decreases without bound, the graph of f(x) increases.
Step-by-step explanation:
According to the graph, the end behaviour of the function in the image is decreasing without bound. When we graph a function, with put an arrow to indicate when a function increases or decreases without bound, that's why in this case we can say the decreases without bound, the function extends without limit.
Therefore, as the x increases, f(x) decreases. If you carefully pay attention to the graph, x is constantly increasing in the right end, and f(x) is more and more close to the x-axis.

Greg bought a jacket for $35.23, a flag for $10.75, and a baseball cap for $17.25. He paid $50 and
the rest he borrowed from his friend. If Greg got $6.77 in change from the cashier, how much did he
borrow from his friend to pay for all the items?
Answer:
His friend gave Greg a 20$ bill.
Step-by-step explanation:
35.23+10.75+17.25=63.23
63.23-50= 13.23
13.23+6.77= 20
Answer:
He borrowed $6.46
Step-by-step explanation:
Add the totals up together. 35.23 + 10.75 + 17.25 to get 63.23
Subtract 50 from 63.23 (63.23 - 50.00) to get 13.23.
Subtract 6.77 from 13.23 (13.23 - 6.77) to get 6.46.
He borrowed $6.46 from his friend!

The average age of the seven apprentice magicians is 143 years. The average age of the seven apprentice magicians and the head wizard is 150 years. How old is the head wizard in years? Please need answer ASAP!!!!!!!!
Answer:
it would be 200 points. Lets assume that all of the apprentice magicians are 143 years old. If so, then 143 x 7 = 1001. 1001 + 200 = 1201. 1021 ÷ 8 (the number of magicians) the answer is 150. so the age of head wizard is actually 200 years.
