Ab is dilated from the origin to create a'b' at a' (0,6) and b' (6, 9). what scale factor was ab dilated by?
1/2
2
3
4

The scale factor was 3

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

step 1

Find the distance AB

we have

A(0,2) and B(2,3) -----> see the figure

substitute in the formula

step 2

Find the distance A'B'

we have

A'(0,6) and B'(6,9) -----> given value

substitute in the formula

simplify

step 3

Find the scale factor

To find out the scale factor divide the length of the image A'B' by the length of the pre-image AB

so

therefore

The scale factor was 3

(x+3)(x+7)

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
