Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2

You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1

The equation you seek is
.. y = x^2 +6x +7

Masja [62]

Answer:

7370

Step-by-step explanation:

Let x represent attendance before drop.

We have been given that an article reports attendance dropped 7% this year, to 6854. We are asked to find the attendance before the drop.

Since attendance dropped by 7%, this means that attendance after drop was 93% of x.

We can represent this information in an equation as:

$x-\frac{7}{100}x=6854$

$x-0.07x=6854$

$0.93x=6854$

$\frac{0.93x}{0.93}=\frac{6854}{0.93}$

$x=7369.89247$

$x\approx 7370$

Therefore, the attendance before drop was 7370.
