Answer:

-3

Step-by-step explanation:

y = -2x+4y

It is given (_,-2), (x,y).

We must find the x coordinate.

Put y as -2.

(-2)= -2x+4(-2)

-2 = -2x+-8

2x = -8 + 2

2x = -6

2x/2 = -6/2

x = -3

Answer:

-3

Step-by-step explanation:

1. Plug in -2 for y, because it is the y value in the coordinates

2. Simplify -2 = -2x + 4(-2)

3.That simplifies to -2 = -2x - 8

4. Add 8 to both sides to get 6 = -2x

5. Divide both sides by -2

6. x = -3

Find the midpoint of the line segment joining points A and B. A(2, - 5); B(4,1)

Nookie1986 [14]

Answer:

(3, -2)

Step-by-step explanation:

Find the midpoint coordinates (x, y) of points A(2, - 5) and B(4, 1)

x-coordinate of the midpoint is (2+4)/2 = 6/2= 3

y-coordinate of the midpoint is (-5+1)/2 = -4/2= -2

The mid point coordinates are (3, -2)

A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater

Shtirlitz [24]

Attendance with the higher ticket price is ...

... $1750/$7 = 250

So the percentage change in attendance is ...

... change = (new - original)/original × 100%

... = (250 -300)/300 × 100% = -1/6×100% ≈ -17%
