This figure is dilated by a factor of 12, with the origin as center.

which statement is not correct?

a)r(2, 8) → r'(1, 4)

b)q(10, 2) → q'(5, 2)

c)p(2, -4) → p'(1, -2)

d)s(-10, 2) → s'(-5, 1)

The one that stands out as incorrect is B

Step-by-Step Explanation:

I'll assume that by 12, you meant 1/2 because if the scale factor is 12, then none of the choices are correct. B is the only one that stands out because while in the x, 10 does turn into 5 after being multiplied by 1/2, the 2 in the y remained the same instead of being turned into 1.

This figure is dilated by a factor of 12, with the origin as center.  

Which statement is NOT correct?

A)R(2, 8) → R'(1, 4)

B)Q(10, 2) → Q'(5, 2)

C)P(2, -4) → P'(1, -2)

 D)S(-10, 2) → S'(-5, 1)

Step-by-step explanation:

As you can see in A,C and D, the x-coordinate and the y-coordinate is divided by 2.

E.g.  2 / 2 =1     8/2=4    so ⇒R'(1, 4)  

but in B, the first x-coordinate is divided by 2 but the y-coordinate is divided by 1.

I thought I already answered B.

Step-by-step explanation:

B. 1.55 x 106

Step-by-step explanation:

This is an example of the distributive property. In order to turn it back to the regular form, you need to do this:

3.40

-

1.85

1.55      

Don't forget to put the 106!

3.40

-

1.85

1.55      x       106

You can do it in both forms and get the same answer. It depends on what the question asks for or whichever form you like best/you think is the easiest.
