Repost 8th grade 50 POINTS+BRAINLIEST: How do you graph a quadratic equation in vertex form when the equation is a perfect squar e? Use x² -4x+4 as an example
2 answers:
1(x-2)^2+0 is the vertex form
Answer: Vertex : Maximum (2, 0)
Rules:
(x + d)² = x² + 2dx + d² and (x - d)² = x² - 2dx + d² x² + 2dx = (x + d)² - d² and x² - 2dx = (x - d)² - d²
Solve:
x² - 4x + 4
x² - 2(2x) + 2²
(x - 2)²
Into vertex form: a(x - h)² + k
1(x - 2)² + 0
Identify:
vertex : (h, k) = (2, 0)
Find additional things, to graph the equation:
(i) x-intercept: (2, 0)
(ii) y-intercept: (0, 4)

Answer:
420 Mile's.
Step-by-step explanation:
First you figure out the unit rate by dividing 360 by 6 which is 60. So that's 60 miles per hour. Now multiply 60 by 7 to find out how many miles she will drive in 7 hours. When you multiply you get 420.
Answer:
X² - 5 = 0
x² = 5
square on both side
x = 5²
x = 25
May mine aswer might be wrong please retrify but as per my point of view it will be write
Negative times negative = positive.
The answer would probably be D because you don't know what x is.
