5. In the triangle ABC, M is the midpoint of [AB] and N is the midpoint of [CM].
rusak2 [61]

Answer:

The coordinate or the point N is (2,3)

Step-by-step explanation:

The formula for the midpoint of two points is;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

for AB

A(-1,3) and B (7,-3)

We have;

(x,y) = (-1 + 7)/2 , (3-3)/2 = (6/2, 0/2) = (3,0)

For CM;

C(1,6) and M(3,0)

(x,y) = ( 1 + 3)/2, (6+0)/2 = (4/2, 6/2) = (2,3)

Find an expression which represents the sum of (-3x-4y)(−3x−4y) and (x+3y)(x+3y) in simplest terms
ella [17]

Answer:

The sum of (−3x−4y) and (x+3y) in simplest terms will be:

\left(-3x-4y\right)+\left(x+3y\right)=-2x-y

Step-by-step explanation:

Given

  • (−3x−4y)
  • (x+3y)

Finding the sum of (−3x−4y) and (x+3y)

\left(-3x-4y\right)+\left(x+3y\right)

=-3x-4y+x+3y

=-3x+x-4y+3y

=-2x-4y+3y

=-2x-y

Therefore, the sum of (−3x−4y) and (x+3y) in simplest terms will be:

\left(-3x-4y\right)+\left(x+3y\right)=-2x-y

Two column proof 2n-21=n/4
natita [175]

Simplifying:

2n-21=0.25n


We move all terms containing n to the left and all other terms to the right.

+2n-0.25n=+21


We simplify left and right side of the equation.

+1.75n=+21


We divide both sides of the equation by 1.75 to get n.

n=12
