ollegr [7]

Answer: 7.2$

hope it helps :)

step-by-step explanation:

Cost of each box = 3$

Cost of 3 boxes without 20% coupon = 9$

With 20% off Coupon = 9 by 100 multiplied by 20

(the zero's cut with each other leaving)

= 9 by 10 multiplied by 2

(9 multiplied by 2 = 18)

= 18 by 10

(18 divided by 10 = 1.8)

= the 20% of 9$ is equal to 1.8

when subtracted with the total cost leaves 7.2$

Answer: A M (2,-3) and N ( 4,1)

Step-by-step explanation:

(-2, 3) after a 180 degrees rotation the coordinates will be in the fourth quadrant (2,-3) and the y coordinate is always negative in the fourth quadrant.

(-4,1) after a 180 degrees rotation the coordinates will be in the first quadrant (4,1) and all the coordinates will be positive.

Find the area of a triangle whose vertices are (0,0), (4,2), (-1,2)

Yakvenalex [24]

Answer:

Therefore area of a triangle whose vertices are (0,0), (4,2), (-1,2) is

5 units².

Step-by-step explanation:

Given:

Let the vertices be,

point A( x₁ , y₁) ≡ ( 0 , 0)

point B( x₂ , y₂) ≡ (4 , 2)

point C(x₃ , y₃ ) ≡ (-1 , 2)

To Find:

Area of Triangle = ?

Solution:

If the Vertices A( x₁ , y₁), B( x₂ , y₂) and C(x₃ , y₃ ) then the Area of Triangle is given by

$\textrm{Area of Triangle}=\dfrac{1}{2}(x_{1}(y_{2}-y_{3})+x_{2}(y_{3}-y_{1})+x_{3}(y_{1}-y_{2}))$

Substituting the values we get

$\textrm{Area of Triangle}=\dfrac{1}{2}(0(2-2)+4(2-0)+(-1)(0-2))$

$\textrm{Area of Triangle}=\dfrac{1}{2}(0+8+2))=\dfrac{10}{2}=5\ units^{2}$

Therefore area of a triangle whose vertices are (0,0), (4,2), (-1,2) is

5 units².
