Answer:
-7
Step-by-step explanation:

Answer:
The smaller exterior angle is the exterior angle in the vertex P, and it measures 90°
Step-by-step explanation:
The sum of the internal angles of a triangle needs to be 180 degrees, so we have two equations:


Substituting
by
in the second equation, we have:


The other two angles need to be lesser than mP, and the exterior angle is the supplement of the internal angle, so the bigger the internal angle, the smaller the exterior angle.
So if the bigger internal angle in this triangle is mP, the smaller exterior angle is also the angle in the vertex P:


Answer:
The vertex of this graph is (5, 3)
Step-by-step explanation:
In order to find the vertex of any graph in vertex form, we need to look at the base form.
f(x) = a|x - h| + k
The point (h, k) is the vertex. You can see that 5 lines up with the h term and 3 lines up with the k term. This gives us a vertex of (5, 3)
Answer:
f(x)=1
Step-by-step explanation:
f(0)=-0+1
=1
