Answer:
y - 3 = 2(x + 1)
y - 3 = 2x + 2
y = 2x + 5
Step-by-step explanation:
Answer:
Third option

Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (-1, 5)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (-1, 5), the equation sought is:


Therefore the answer is the Third option.

Answer:
B or 108
Step-by-step explanation:
we know that the line splits the 90 angle, so the other side is 54
Since it is a isosceles triangle, the base angles are the same and they are both 54 degrees.
The sum of all the angles in a triangle is 180, so 180-54-54 is 72.
Since the line intersecting the triangle is a straight angle 180, we do 180-72=108
