Answer:

The scale factor is \frac{1}{2}.

Step-by-step explanation:

The dilation of a point about the origin with scale factor k is defined as

P(x,y)\rightarrow P'(kx,ky)            ..... (1)

It means the scale factor is calculated as

k=\frac{\text{x coordinate of image}}{\text{x coordinate of preimage}}

The given dilation is defined as

(10,0)\rightarrow (5,0)                ..... (2)

From (1) and (2) we get,

x coordinate of image = 5

x coordinate of preimage = 10

k=\frac{5}{10}

k=\frac{1}{2}

Therefore the scale factor is \frac{1}{2}.

H=4(x+3y)+2 make x the subject
blagie [28]
H = 4(x + 3y) + 2
H = 4x + 12y + 2
H - 12y - 2 = 4x
(H - 12y - 2) / 4 = x or 1/4H - 3y - 1/2 = x
