Let me walk you through this real quick:
-4x + 9 (10x - 1)
-4x + 90x - 9 (open up the brackets)
90x - 4x - 9
= 86x - 9
B. Standard form
Hope this helps
Using (a-b)(a+b)= a2-b2
Simply the product
x2-62
Evaluate the power
x2-36
Answer:
B(-3, -3)
Step-by-step explanation:
If a point O(x, y) divides line segment XY in the ratio of n:m and the endpoints of the segment are
, the coordinates of O is:

Given that A(6, -6) and C(-6, 2). Pont B is on AC such that:
AB = (3/4)AC
AB/AC = 3/4
Therefore point B divides the line AC in the ratio of 3:1. Let point B be at (x, y), therefore:

Therefore the location of B is at (-3, -3)
