The commutative property only works under addition and multiplication properties.
Answer:
AC =4DB
Step-by-step explanation:
D is midpoint of AB .So, AD = DB
AB = 2DB ---------- (i)
B is the midpoint of AC.So, AB = BC
AC = 2AB
= 2*2DB {FROM 1}
=4DB
Answer:
=7/4 - 9/4 = -2/4
Step-by-step explanation:
1¾ = (4×1+3)/4
2¼ = (4×2+1)/4
The distance between both lines is 2.24 units
Step-by-step explanation:
There is no straight method to find the distance between two lines. The distance can be found out by finding a point on one line and then finding the distance of that point from the other line. The y-coordinate of point is obtained by putting any value of x in equation . The x and y combined give us the point.
Given

We have to find the distance of this point from y=2x+5

The formula for finding distance of a point (x,y) from a line is:

A=2
B=-1
C=5
Putting the values in the formula

Rounding off will give: 2.24 units
The distance between both lines is 2.24 units
