HELP URGENT WILL GIVE BRAINLIEST

Mathematics
1 answer:
sesenic [268]3 years ago
7 0

Answer:

B: (x + 1) = (y - 2)²

Step-by-step explanation:

0 = y² - x - 4y + 3

We want to find the equation of the parabola in vertex form.

The format for the vertex form is;

y = a(x - h) + k

Where (h, k) is the coordinate of the vertex.

Thus, let's transform 0 = y² - x - 4y + 3 into the vertex form

Let's rearrange to get;

x - 3 = y² - 4y

Let's use method of completing the square to get right hand side;

x - 3 = (y - 2)² - 4

Add 4 to both sides to get;

x - 3 + 4 = (y - 2)²

(x + 1) = (y - 2)²

Which of the following is not true about lines of symmetry?
taurus [48]
The statement that is untrue about lines of symmetry is C. A line of symmetry is a vertical line through the middle of a figure.

While this is one example of a line of symmetry, the line doesn’t have to be vertical every time. As stated in answer choice B, lines of symmetry can come from any direction, as long as it evenly splits the figure. This can be vertical, horizontal, and/or diagonal.

I hope this helps. :)

Substiute<br> y=3x-15 <br>4x+2y=22
Nostrana [21]
You can solve it by replacing the Y in the 2nd equation with the solved Y in the first.

4x + 2(3x-15)= 22

that should give you...

4x + 6x - 30 = 22

then combine like terms...

10x - 30 = 22

now we need to get X alone so add 30 to each side....

10x = 52

now divide both sides by 10..
X = 52\10

both are divisible by 2...

X = 26\5

you should be done unless you need Y as well then go back to the first and plug in what you found for X...

Y = 3(26÷5)- 15

and that should give you Y.

a 2nd method you can make your own answer by making x = 0 ..

Y= 3(0) -15

Y= -15

now put that in the 2nd for Y...

4x+ 2(-15) = 22...

4x-30= 22

add 30 to both sides..

4x = 52

divide by 4....

X = 13

now take this to the first for x...

Y= 3(15) - 15

Y = 30

you can check your work by plugging in the two on top and see if the final is the same..

30 = 3(15) - 15

the 2nd way is faster though of course..

anyway X= 13 Y= 30

Ax-bx+y=z which of the following represents the formula that could be used to find x?
Alex73 [517]

Step by step explanation:

You first subtract z on both sides of the equal sign

ax-bx=(z-y)

Since a and b both have a "x" you can subtract them

(a-b)x=(z-y)

then you divide "x" on both sides of the equal sign

\frac{a - b}{x}   = \:  \frac{z - y}{x}
