Step-by-step explanation
b and c would result in a decimal
and d) v2 isnts a number or a variable
Answer:
A) AAS
Step-by-step explanation:
The two pairs of angles are given and they also share a side, meaning that side is congruent to itself, so they are congruent because of Angle Angle Side (AAS)
Answer:
I believe it is C) decreasing when x > -1
Step-by-step explanation:
If you plot all 3 points on a graph, you will notice that the parabola is facing downwards. This means that on the left side of the vertex, it is increasing (the y-value increases). On the right side of the vertex, it decreases (y-value decreases). Note that "decreasing" refers to the y values.
So, since the vertex's x-value is -1 (we know this from the point (-1, 2)), any x-value greater than -1 will be to the right of the vertex. For example, 0, 1, 2, 3, etc. are all greater x-values than -1, so they are all to the right of -1. Since they are on the right, that means the corresponding-values will be decreasing.
Therefore, when x > -1, the parabola is decreasing.

Answer:
y=37
Step-by-step explanation:
the addition of the 3 angles is 180°
then 40 + y +29 +2y = 180
69 + 3y =180
3y = 180 -69
3y= 111
y =111 ÷ 3
y = 37
