<h2>Answer:</h2>
  • The given equation is already in vertex form.
  • The vertex is located  at (7,-8)
<h2>Step-by-step explanation:</h2>

We Know that a standard form of a quadratic equation is given by:

                  y=ax^2+bx+c

where a,b and c are real numbers

and the vertex form is given by:

                 y=a(x-h)^2+k------------------(1)

where the vertex of the function is at: (h,k)

Here we have the function as:

          y=-3(x-7)^2-8

We observe that the equation matches the equation as in equation (1) ; such that a= - 3, h=7 and k= -8

Hence, the equation is already in vertex form and the vertex is at (7,-8)

Sloan [31]

Answer:

It will take Tara 3 hours to get to Nashville. If they meet, it would take them 1 hour and 46 minutes or 1.766 hours.

Step-by-step explanation:

Divide 212 miles by 65 mph: 212÷65=3.2 and 3.2 rounded is 3. They will each drive half the way if they meet in the middle, so 212 miles divided by 2 is 106. Divide that by 60: 106/60=1.766. That is equivalent to 1 hour and 46 minutes.

Tuition for one year at the community college Sean would like to attend is about $8,880. Sean plans to save money each month for
REY [17]

First make an equation then solve for the variable.

8,800 is the end goal so that is what it is going to equal

Since his parents are contribuating 6,000 we can add that as a constant

Now it says in 2 years but it askes us in months so we times 2 by 12 to get 24 months he will be saving.

Now it is asking us how much he should save per month be we don't know that so that is our variable.

8,800 = 24x + 6,000

Solve

8,800 - 6,000 = 24x

2800/24 = x

116.67 = x (rounded for currency)

Sean would have to save $116.67 a month in order to pay for the community college

If I remember correctly perpendicular means right angle so I do not think it could be reversed.
