If triangle abc is defined by the coordinates a(3, 6), b(7, 6), c(7, 3) is dilated by a scale factor of 3, with resulting vertex a' at (9, 18). what is the center of the dilation? a) (0, 0) b) (3, 6) eliminate c) (9, 18) d) (6, 12)

Explanation:

A = (3,6)

A ' = (9, 18)

Each coordinate has been multiplied by the same value, in this case 3

3*3 = 9

6*3 = 18

Because (x,y) turned into (3x, 3y), this means we dilated with the origin as the center of dilation. The origin is a special name for the point (0,0). This is where the x and y axis meet.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
