Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total
ololo11 [35]

Answer:

Step-by-step explanation:

c + f = 16......c = 16 - f

340c + 910f = 9430

340(16 - f) + 910f = 9430

5440 - 340f + 910f = 9430

-340f + 910f = 9430 - 5440

570f = 3990

f = 3990/570

f = 7 <====== 7 first class tickets bought

c + f = 16

c + 7 = 16

c = 16 - 7

c = 9 <====== 9 coach tickets bought

I need help with these questions for Quadratic functions
STALIN [3.7K]

9514 1404 393

Explanation:

1. The general form of a quadratic in standard form* is ...

  f(x)=ax^2+bx+c

An example is ...

  f(x)=2x^2+3x-5

The constant c is the y-intercept, so is the easiest bit of information to obtain in this form.

__

2. The general form of a quadratic in vertex form can be written as ...

  f(x)=a(x-h)^2+k

An example is ...

  f(x)=2(x -3)^2 -5

The ordered pair (h, k) is the vertex of the parabola, so is easy to obtain in this form. Arguably, it may be easier to identify the line of symmetry, x=h, since that requires looking at only one constant, instead of two.

_____

* In the UK, "standard form" is vertex form.
