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
Answer:
<h3>im guessing x represents multiplication. so the
answer is 3</h3>
Step-by-step explanation:
Step-by-step explanation:
7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
7 : x = 2 : 3
- divide 7 by 2.
7/2 = 3.5
- this is the scale factor.
- now multiply this by 3.
3 X 3.5 = 10.5
so, x = 10.5
