Answer:
390
Step-by-step explanation:
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).
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.
