Answer:
triangle ABD> triangle BDC answer is B
Step-by-step explanation:
reason is because A-D is 5 while B-C is 4.5 the other sides are equal so ABD is larger

Answer:
199
Step-by-step explanation:
plug in x=19.6, then
g(19.6) = 10 * 19.6 +3= 199
 
        
             
        
        
        
Answer:
Infinite solution
Step-by-step explanation:
There is 3 possible solutions to a system of linear equations:
- One solution - two distinct lines that do not share y-intercept or slop intersect at a point
- No solution - two distinct lines that share the same slope but not the same y-intercept never intersect and are parallel
- Infinite solution - one distinct function represented two ways which in simplest form share the same slope and y-intercept
The first equation is in simplest form y=2x+3.
The second equation 2y=4x+6 when simplified becomes y=2x+3. 
These are the same lines with the same slope and y-intercept. Therefore, they have infinite solutions.
