Y=5-2x
x^2 + (5-2x)^2 = 25
x^2 + 25-20x+4x^2 = 25
x^2 +4x^2-20x+25=25
5x^2 -20x=0
x=0 and y=5
The slope-intercept form: y = mx + b
m - a slope
b - y-intercept (0; b)
-y + 8x = 2x |subtract 8x from both sides
-y = -6x |change signs
y = 6x
Answer: The slope m = 6, y-intercept b = 0 -> (0; 0).
It would be 5.5y because y equals 1.
Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form
