Answer = 127 degrees
Firstly, find out how many degrees in total are in the polygon.
(n stands for number of sides)
(n - 2) x 180
(6 - 2) x 180 = 720
Afterwards, subtract that amount by all the given angles.
720 - 112 - 133 - 128 - 100 - 120 = 127 degrees
Hope it helps :D
Step-by-step explanation:
You can solve systems of equations using either substitution or elimination. For these problems, I recommend elimination. I'll do the first one as an example.
-3x + 16y = 9
-4x + 8y = 12
Multiply the second equation by -2.
8x − 16y = -24
Add to the first equation (notice the y's cancel out).
(-3x + 16y) + (8x − 16y) = 9 − 24
5x = -15
Solve for x.
x = -3
Now you can plug this into either equation to find y.
-3(-3) + 16y = 9
9 + 16y = 9
y = 0
The solution is (-3, 0).

<h3>Answer: B) $878.28</h3>
================================================
Explanation:
She starts off $16.75 in debt
Later on she deposits $16.75 to get completely out of debt and make the balance 0. This is after depositing the $5.72
So far her balance is $5.72
Add on $872.56 to get 5.72+872.56 = 878.28
-------------
This is what your steps may look like
-16.75 + (5.72 + 16.75)
-16.75 + (16.75 + 5.72)
(-16.75+16.75) + 5.72
(0) + 5.72
5.72
5.72+872.56
878.28
Answer:
D. The axis of symmetry is the y-axis.
Step-by-step explanation:
The vertex is at coordinates (0, 3). Since this parabola opens vertically, its axis of symmetry is the x=coordinate of the vertex: x = 0. That is the equation of the y-axis.
The axis of symmetry is the y-axis.
