ABC=140
because 180-40=140
This is the concept of translation;
Given that triangle A (-1,3), B(-1,1), C(3,1) has been translated to A'(2,-1), B'(2,-4), C(6,-4)
the from the diagram we see that the coordinates of the triangle ABC have been moved by 3 units to the right while the y coordinates have been moved by 5 units down to form A',B',C'.
We therefore conclude that the correct statement is:
Triangle ABC has been translated 3 units to the right and 5 units down.
A penny is worth 1 cents. So, 84 pennies is 84 cents or $0.84
A dime is worth 10 cents, So, 300 dimes is 30 dollars or $30 dollars
$0.84 + $30 = $30.84
84 pennies and 300 dimes is equivalent to 30 dollars and 84 cents.
Sorry about the drawing but the line starts at the origin of the graph and since it is -x which means it has a negative slope. So the line would start at the origin going down by the slope of -1. hope this makes sense
