Repost 8th grade 50 POINTS+BRAINLIEST: How do you graph a quadratic equation in vertex form when the equation is a perfect squar
Naddika [18.5K]

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)

What is the value of x?
nalin [4]

Answer:

  x = 42.9 m

Step-by-step explanation:

Corresponding sides of similar triangles MAB and MNP are proportional. This means ...

  x/MP = MA/MN

However, we don't have a number for MA yet, so we need to find it.

  MA +AN = MN

  MA = MN - AN            subtract AN

  MA = 67.2 m - 32 m = 35.2 m

Now, we can use this to find x.

  x = MP · (MA/MN) = (81.9 m) · 35.2/67.2

  x = 42.9 m
