Answer:
$2000
Step-by-step explanation:
For each pound, the charge is $40. There are 50 such charges. The point of multiplication is to simplify the process of repeated addition.
... 50 × $40 = $2000
The one in the middle you can tell because when x=0 that is the y intercept and the graph had a y intercept of 4 and the middle graph had 5
its the first one because for example [-12] and 4
the absolute value of -12 is 12 so its greater
yes obtuse angles measure over 90 degrees and less 180 degrees
