Hi there!

To find the x-intercept of the function we need to calculate f(x) = 0.

(x - 4)(x + 2) = 0

Rule AB = 0, gives A = 0 or B = 0.
x - 4 = 0 \: \: \: or \: \: \: x + 2 = 0

Add 4 to both sides or subtract 2 from both sides.
x = 4 \: \: \: \: \: \: \: \: \: \: or \: \: \: x = - 2

Hence, the solutions are:
(4, 0) & (-2, 0)

Given the points A(3, 4) and B (6, 10), find the
Dvinal [7]

Answer:

P (5 , 8)

Step-by-step explanation:

P (x,y) partition A (x₁ , y₁) B (x₂ , y₂) into ratio AM:MB = a:b = 2:1  ... a=2 , b=1

x = (bx₁ + ax₂) / (a+b)

  = (1 * 3 + 2 * 6) / (2 + 1)

  = 15/3

  = 5

y = (by₁ + ay₂) / (a+b)

  = (1 * 4 + 2 * 10) / (2 + 1)

  = 24/3

  = 8

P (5 , 8)
