Answer:

3 hours

Step-by-step explanation:

Let the number for hours afterward be represented as: x

The veteran tutor charges $15 for the first session plus $60 per hour afterward.

This is expressed as

$15 + $60 × x

15 + 60x

The new college graduate charges $45 for the first session plus $50 per hour afterward.

$45 + $50 × x

45 + 50x

The number of hours these two must tutor in order to earn the same amount of money is calculated as:

Veteran tutor = New college graduate tutor

15 + 60x = 45 + 50x

60x - 50x = 45 - 15

10x = 30

x = 30/10

x = 3 hours

Therefore, the number of hours these two must tutor in order to earn the same amount of money is 3 hours

The vertex form of the equation of a parabola is y=2(x+4)^2-7. What is the standard form of the equation.
Elan Coil [88]

Answer:


Step-by-step explanation:

To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:

y = 2[x^2 + 8x + 16 - 7], or

y = 2[x^2 + 8x + 9],

or y = 2x^2 + 16x + 18

None of the given possible answers match.  The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).

The answer is 400.000+ 10.000+ 2.000+ .600+ .030+ .008

I came to this conclusion because I took each number and replaced all of the other numbers with the place holder "0".
