Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
Step-by-step explanation:
500/600x = 0
thè answer is 0 i guess
50 bc since all the angles in a triangle are 180 degrees the other angle in the complete triangle is 40 degrees and since the lines are parallel it would be a corresponding angle to the angle beside x, then you would take 90+40 +x= 180 bc it’s a straight angle
you would get 50
x² + y² – 10x + 6y + 18 = 0
x² – 10x + y² + 6y + 18 = 0
x² – 10x + 25 - 25 + y² + 6y + 9 - 9 + 18 = 0
(x-5)² + (y+3)² -16 = 0
(x-5)² + (y+3)² = 16
(x-5)² + (y+3)² = 4²
Center at (5,-3) radius = 4
Part 2
1. Complete the square for x and y
2. Put in the format for a circle. (x-h)² + (y-k)² = r², center at (h,k) with radius = r
