Orlando is doing a math problem where he needs to dilate a triangle by a scale factor of four. The ordered pairs for his pre-ima
Rainbow [258]
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.
Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.

On this exercise is given that a triangle with vertices (-2,1), (8,4), and (3,0) was dilated by a scale factor of four, and it is asked to find the vertices of the image of the triangle after the dilation occurred.

Pre-image                       Image
(-2,1)  --   (-2*4,1*4)   --   (-8,4)
(8,4)   --    (8*4,4*4)   --    (32,16)
(3,0)   --    (3*4,0*4)   --    (12,0)

The coordinates representing the vertices of the triangle's image are (-8,4), (32,16), and (12,0); meaning that the ordered pair which is not a coordinate for a point in the triangle's image is (2,1).

iragen [17]

Answer:

The expression of total amount David paid is

y=25+ 15x

where y represents total amount in dollar, x is time in hour.

The total amount that David paid is $100.

Step-by-step explanation:

Given that,

Ronnie's Rentals charges $25 plus $15 per hour to rent a chain for 5 years.

Let

Ronnie's rents a chain for x hours.

Given that,

Rental charge of a chain for 1 hour is $15

Rental charge of a chain for 2 hour is $(15+15) = $30 = $(2×15)

Rental charge of a chain for 3 hour is $(15+15+15) = $45 = $(3×15)

From the above we conclude that,

∴Rental charge = Time ×$15

Rental charge of a chain for x hour is = $(x.15)=$15x

The expression of total amount David paid is

y=25+ 15x

where y represents total amount in dollar, x is time in hour.

Now plugging x= 5 in the above expression

y= 25 + (15×5)

  =$100

The total amount that David paid is $100.
