Answer:
6 3/10 mph.
Step-by-step explanation:
Add 4 of both sides leaving you with
3/2x=20
Then multiply both sides by 2/3 giving you x=3
GCF = 14
As 14*2=28
LCM = 1
As 1*14=14
As 1*28=28
Answer:
The domain of function
is set of all real numbers.
Domain: (-∞,∞)
Step-by-step explanation:
Given:


the domain of both the above functions is all real number.
To find domain of :

Substituting functions
and
to find 

The product can be written as difference of squares. ![[a^2-b^2=(a+b)(a-b)]](https://tex.z-dn.net/?f=%5Ba%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29%5D)
∴ 
The degree of the function
is 2 as the exponent of leading term
is 2. Thus its a quadratic equation.
For any quadratic equation the domain is set of all real numbers.
So Domain of
is (-∞,∞)
< BDM = 45 <==
DM ( the angle bisector) divides < BDJ into 2 equal angles. And since < CDJ = 90, < BDJ = 90.....and the bisector splits < BDJ into 2 equal angles, so < BDM = 45 and angle JDM = 45
