The number of sides is the same as the number of lines of symmetry and the order of rotational symmetry.
So, a regular decagon would have 10 lines of symmetry.
A- Perpendicular lines have negative reciprocal slopes. Therefore a perpendicular line to 2x-8 will have a slope of -1/2. Once solved in slope intercept form, choice A shows a line of slope -2/4, equivalent to -1/2
Answer:
-4
Step-by-step explanation:
f(-1) = 2(-1) - 2 = -4
Answer:
1. $33.00
2. $48.00
3. $3.00
4. $36.40
Step-by-step explanation:
44.00 - 25% = 33 —> $33.00
80.00 - 40% = 48 —> $48.00
9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00
52.00 - 30% = 36.4 —> $36.40
