ΔABC is dilated by a scale factor of 0.25 with the origin as the center of dilation, resulting in the image ΔA′B′C′. If A = (-1,

Leni [432]

Answer:

Step-by-step explanation:

To find B and C prime, you must multiply them by .25, or 1/4.

B' =

(-2 x .25),(1 x .25)

I did mine in fraction form, because it will prove to be more useful in future mathematics.

B' = (1/2 , 1/4)

Repeat the process with C.

C' =

(14 x .25),(17 x .25)

C' =

(7/2 , 17/4)

You only need to focus on B and C because you are finding the length of B'C'.

The formula for distance is the square root of x to the sub of 2 minus x to the sub of 1 squared minus y to the sub of 2 minus y to the sub of 1 square.

x2 - x1 = 7/2 - 1/2 = 6/2 = 3 squared = 9

y2 - y1 = 17/4 - 1/4 = 16/4 = 4 squared = 16

16 + 9 = 25

Square root of 25 is 5.

Therefore, the distance is 5.

Please help ! :0 -17 = 2y/3 + 3y/4

VashaNatasha [74]

Hi,

Equation;

$- 17 = \frac{2y}{3} + \frac{3y}{4}$

Solving:

$- 17 = \frac{2y}{3} + \frac{3y}{4} \: \: \: | \div 12 \\ - 204 = 8y + 9y \\ - 204 = 17y \\ 17y = - 204 \: \: \: | \div 17 \\ \\ y = - 12 \: \: \: \: \: \: \: \: (result)$

Hope this helps.
