Is quadrilateral jklm the result of a dilation of quadrilateral abcd by a scale factor of 2? why or why not?
4vir4ik [10]

No. Because sides JM and KL have different slopes from sides AD and BC .

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

For AD:

We have the points A(2, -2) and D(1, -4). Substitute:

m=\dfrac{-4-(-2)}{1-2}=\dfrac{-2}{-1}=2

For JM:

We have the points J(4, -4) and M(2, -9). Substitute:

m=\dfrac{-9-(-4)}{2-4}=\dfrac{-5}{-2}=2.5

2\neq2.5

----------------------------------------

Another argument.

No. Because the MJ is not twice as long as AD.

The formula of the length of a segment:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The length of AD:

|AD|=\sqrt{(1-2)^2+(-4-(-2))^2}=\sqrt{(-1)^2+(-2)^2}=\sqrt{1+4}=\sqrt5

The length of MJ:

|MJ|=\sqrt{(2-4)^2+(-9-(-4))^2}=\sqrt{(-2)^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}

\sqrt{29}\neq2\sqrt5

maxonik [38]

Answer:

B 4

Step-by-step explanation:

She bought 2 jackets

Jackets = 2*49 = 98

She bought 3 sweaters

Sweaters = 3 * 25 = 75

The costs for the jackets and sweaters is 98+75 =173

She spent a total of 185

185-173 = 12

She spent 12 dollars on socks

Socks are 3 dollars each

12/3 = 4

She bought 4 pairs of socks

   Hope this helps! Do all the others in same manner!!

2) 12/24 * 100 = 1200/24 = 50%

3) 25/208 * 100 = 2500/208 = 12.01%

4) 60/188 * 100 = 6000/188 = 31.91%

5) 24/44 * 100 = 2400/44 = 54.54%

Hope this helps!
