a. 18 cars; 20 motorcycles
b. 14 cars; 24 motorcycles
c. 11 cars; 27 motorcycles
d. 16 cars; 22 motorcycles
it has rotational symmetry about the origin.
if we rotate it 180 degrees about the origin we get the same graph.
another rotation of 180 degrees also gives the same graph, so we have a rotational symmetry of 2.
-20x - 8
the standard form as
given: a function which is written in vertex form or intercept form.
we have to re-write it in standard form that in terms of
squaring using , we get,
multiply 5 inside , we get,
solving further , we get,
thus , we have obtained the standard form as
25 minus 17 is 8, 25 is bigger than 17 so the answer would be a negative.
