The equation represents a parabola with a vertex at (1,3) opening downward.
What is a parabola?An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola.
A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
The given equation is 3x² - 6x + 4y - 9 = 0. On plotting the graph of the given equation it is found that the parabola formed is opened downwards and has a vertex at the point ( 1,3). The graph is attached with the answer below.
Hence, the correct option is C which is the equation that represents a parabola with a vertex at (1,3) opening downward.

Answer:
20/9
Step-by-step explanation:
16/9 * 5/4
4/9 * 5
20/9
The quotient of dividing the given fractions is 20/9.
Given that, 1 7/9=16/9 and 4/5.
From the given fractions we need to divide 16/9 by 4/5.
How to divide the fractions?A fraction represents a part of a whole or, more generally, any number of equal parts.
The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
Now, 16/9÷4/5
Change ÷ to × and reciprocate 4/5 to 5/4.
Then, 16/9÷4/5=16/9×5/4=20/9
Therefore, the quotient of the given fraction is 20/9.

To find:
The value of x.
Solution:
Draw a line segment OA as shown below.
In triangle ABO,
[tex]OA=OB[/tex] [Radii of same circle]
[tex]m\angle BAO=m\angle ABO=20^\circ[/tex] [Base angles of an isosceles triangle]
In triangle ACO,
[tex]OA=OC[/tex] [Radii of same circle]
[tex]m\angle CAO=m\angle ACO=30^\circ[/tex] [Base angles of an isosceles triangle]
Now,
[tex]m\angle BAC=m\angle BAO+m\angle CAO[/tex]
[tex]m\angle BAC=20^\circ+30^\circ[/tex]
[tex]m\angle BAC=50^\circ[/tex]
Central angle is always twice of angle subtended by two points on the circle.
[tex]m\angle BOC=2\times m\angle BAC[/tex]
[tex]x=2\times (50^\circ)[/tex]
[tex]x=100^\circ[/tex]

A: y = 12 - x
B: y = 12x
C: y = 12 + x
D: y = x under 12
P.S: 12/x to be exact
Answers
Answer:
B
Step-by-step explanation:
we know it has to equal y(the total cost of books). We also know that each book is 12 dollars each. So 12 dollars per book =12x. We add in the y now,
y=12x
because say you have 5 books 5 is x so you would do 5 times 12 because 12 is the cost for each book, 12 times 5 equals 60. but that’s just a example, b is the correct answer.
