Simplify the expression 6h +(-7.7d) – 16 + 5d - 2.6h.

blagie [28]

Answer:

3.4h-2.7d-16

Step-by-step explanation:

Before we even start, we can already simplify some things

For example, in this equation it says +(-7.7d)

We can simplify this to 6h-7.7d-16+5d-2.6h

Now we have to get all of the common variables together

So the d’s and h’s have to be combined together in this equation

This makes a new equation of 3.4h-2.7d-16

That is our answer!

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio.

Nesterboy [21]

Answer:

P(-11 , 14)

Step-by-step explanation:

<u>Explanation:-</u>

Given points A(-6, 9), B(2, 1); Ratio 5 : 3

The Point P divides the directed line segment from A to B in the given ratio Externally

5 : 3

A( -6,9) B(2,1)

we will use formula

= $(\frac{5(1)-3(9) }{5-3} ,\frac{5(2) -3(-6)}{5-3})$

= $(\frac{5-27}{2} , \frac{10+18}{2} ) = (-11 , 14)$

The point P( -11 ,14) divides the directed line segment from A to B in the given ratio Externally
