Divide by 2, then subtract 4
lara [203]3 years ago

Answer:

Divide by 2

Then subtract 4

Step-by-step explanation:

Let y = 2(x+4)

Exchange x and y

x = 2(y+4)

We want to solve for y

Divide each side by 2

x/2  = y+4

Then subtract 4 from each side

x/2 -4 =y

The inverse is x/2 -4

kolbaska11 [484]
C - fixed costs; b - costs per bicycle;
c + 110 b = 10,900 
c + 130 b = 11,600
c = 10,900 - 110 b
10,900 - 110 b + 130 b = 11,600
20 b = 700
b = 700 : 20 = $35
c + 110 * 35 = 10,900
c + 3,850 = 10,900
c = 10,900 - 3,850
c = $7,050 ( daily fixed costs )
Marginal cost is the cost of producing one more unit of goods ( one more bicycle ).
Answer:
The company`s daily fixed cost is $7,050.
The marginal cost per bicycle is $35.

Find the equation of the line passing
Ostrovityanka [42]

Answer:

  y = 4x -14

Step-by-step explanation:

The required answer form is slope-intercept form, so we need the slope and the y-intercept of the line.

The slope equation is ...

  m = (y2 -y1)/(x2 -x1)

  m = (10 -2)/(6 -4) = 8/2 = 4

The y-intercept equation is ...

  b = y - mx

  b = 2 -4(4) = -14

The equation of the line is y = 4x -14.
