Scaling up a 4 inch by 6 inch image by 50% results in which of the following image size

The size of the image is 4 inch by 6 inch

Size of the image scale up by 50%

4 in increased by 50 % = New length = x

Cross multiply, we get

100 x = 4(50)

100x = 200

Divide both side by 100, to find x

x = 200/100

x = 2

New length = original length + increased length

New length = 4 + 2 = 6 in

6 in increased by 50 % = New length = y

Cross multiply, we get

100 y = 6(50)

100y = 300

Divide both side by 100, to find y

y = 300/100

y= 3

New length = original length + increased length

New length = 6 + 3 = 9 in

So New dimensions are 6 in by 9 in

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

hope this ! have a great day.
