Answer:
C
Step-by-step explanation:
1.75n = 7 ( to isolate n divide both sides by 1.75 )
n =
= 4
Answer:
D
Step-by-step explanation:
Just like with the last time you asked this question, the correct answer is D since the graph is slid 3 to the left. Hope this helps+
The equation of the vertical parabola in vertex form is written as

Where (h, k) are the coordinates of the vertex and p is the focal distance.
The directrix of a parabola is a line which every point of the parabola is equally distant to this line and the focus of the parabola. The vertex is located between the focus and the directrix, therefore, the distance between the y-coordinate of the vertex and the directrix represents the focal distance.

Using this value for p and (3, 1) as the vertex, we have our equation
99
999
9999
ninety-nine
technically this does not start with nine
