A line passes through tge points (1,-3) and (4,6) what is the zero of this line ?

Maru [420]

Answer:

<em>The zero of the line is (2,0)</em>

Step-by-step explanation:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

We are given the points (1,-3) and (4,6). Substituting:

$\displaystyle y+3=\frac{6+3}{4-1}(x-1)$

Operating:

$\displaystyle y+3=\frac{9}{3}(x-1)$

$y+3=3(x-1)$

The zero of this line can be found by making y=0 and solving for x:

0+3=3(x-1)

3=3x-3

Adding 3:

6=3x

Solving:

x = 2

The zero of the line is (2,0)

Oduvanchick [21]

Answer:

1. cost per chair: $86.40

2. selling price per chair: $146.88

Step-by-step explanation:

1. The total cost per chair will be the sum of the cost of materials and the overhead cost (equipment, energy, labor, marketing). The cost of materials is ...

$500/(16 chairs) = $31.25/chair

So, the total cost is ...

cost of each chair = material cost + overhead cost

= $31.25 +55.15

cost of each chair = $86.40

__

2. We assume the markup is 70% of the cost, so will be ...

0.70 · $86.40 = $60.48

Then the selling price of the chair will be ...

selling price = cost + markup

selling price = $86.40 +60.48

selling price = $146.88
