The rectangle shown is dilated by a scale factor of 2.

a) calculate the length of each side of the dilated image.

b) draw the new image and label it a’ b’ c’ d’.

Answer with explanation:

It is given that, The Rectangle , A B CD is , Dilated by a scale factor of 2.

Dimension of Pre-Image

Length of Rectangle ABCD=AB=CD=15 cm

Breadth of Recatangle ABCD=AC=BD=8 cm

→Dilation factor = 2

Dimension of Dilated  Image

Length of Rectangle A'B'C'D'=A'B'=C'D'=15×2=30 cm

Breadth of Recatangle A'B'C'D'=A'C'=B'D'=8×2=16 cm

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

its b
