Answer:
(0, 2)
Step-by-step explanation:
Given the following
coordinate A (-6, 5)
Coordinate C (4, 0)
Ratio is 2:3
Required
Coordinate of B
Using the midpoint formula expressed as;
M(X,Y) = [(ax1+bx2/a+b), ay1+by2/a+b]
x1 = -6, y1 = 5, x2 = 4 and y2 = 0
a = 2 b = 3
Get X;
X = ax1+bx2/a+b
X = 2(-6)+3(4)/2+3
X = -12+12/5
X = 0/5
X = 0
Get Y;
Y = ay1+by2/a+b
Y= 2(5)+3(0)/2+3
Y = 10/5
Y = 2
Hence the coordinate of B is at (0, 2)
Using Sin^2 and Cos^2 identities,
= Cos^2(2A) + 4[(1/2)(1-Cos(2A)][(1/2)(1+Cos(2A)] = 1
= Cos^2(2A) + 1 -Cos^2(2A) = 1
0 = 0
There is nothing to solve for as it is an identity of sorts.

-10x+18
Step-by-step explanation:
combine like terms.
The answer to the equation is 5 7/15
Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
