Answer:
y + 4 = a(x - 7)^2
Step-by-step explanation:
The standard vertex form of a parabola with vertex at (h, k) is
y - k = a(x - h)^2
and if we start with the simplest case, y = a(x)^2 and translate its graph 7 units to the right and 4 units down, we get y - {-4] = a(x - 7)^2, or
y + 4 = a(x - 7)^2

Answer:
<em>y = 8.25x</em>
Step-by-step explanation:
<u>Linear Modeling</u>
Some events can be modeled as linear functions. If a situation comes where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.
The linear function can be expressed in the slope-intercept format:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

Let's use linear modeling to represent Steven's earnings he makes babysitting. Call y the money he charges by x hours of work.
We know he charges y1=$33 for x1=4 hours, and y2=$57.75 for x2=7 hours. The ordered pairs are (4,33) and ( 7, 57.75)
Computing the equation of the line we have:

Operating:



y = 8.25x
There is a proportional relationship.

Step-by-step explanation:
Answer:
The value of A is 1, D is 0, E is -2 and F is 0.
Step-by-step explanation:
The given equation is
...(1)
The standard form of the circle is

Where, (h,k) is the center of the circle and r is the radius.



It can be written as
....(2)
On comparing (1) and (2) we get.




Therefore the value of A is 1, D is 0, E is -2 and F is 0.
