Step-by-step explanation:
A regular n-sided polygon has n axes of symmetry. The angle between two consecutive axes is 360° / n.
In the case of an octagon, the angle is 360° / 8 = 45°.
-2 | 2 4 2 8 8
. | . -4 0 -4 -8
-------------------------------
. | 2 0 2 4 0
which translates to
So here you're using system of equations. You can solve systems by graphing, elimination, or substitution. Ill use substitution. First lets solve for x. take the second equation and add y to both sides to get x by itself:
x - y = 75
x = y + 75 now plug y+75 in for x in the first equation
x + y = 743
(y +75) +y = 743 solve for y
2y +75 = 743 subtract 75
2y = 668 divide both sides by 2
y = 334
now plug this into any of the 2 equations to solve for x i chose the second one
x - y = 75
x - 334 = 75 add 334 to both sides
x = 409
This means x, sold before the tournament is 409 and y, sold at the door is 334. That means the assistant is wrong and accidentally flipped the two answers
Answer:
A
Step-by-step explanation:
A is the answer because the slope is 1 square which you can see from the line and also the y-intercept is 2 which means it is 2 on the y axis. Also please can I get brainly :)
B.
B.
C.
I think these are correct. if not... very sorry.
