A triangle with vertices at A(20, –30), B(10, –15), and C(5, –20) has been dilated with a center of dilation at the origin. The

Answer:

One-fifth

Step-by-step explanation:

step 1

Find the distance between the origin and the point B

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

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

O (0,0) and B(10, –15)

substitute

$d=\sqrt{(-15-0)^{2}+(10-0)^{2}}$

$d=\sqrt{325}\ units$

step 2

Find the distance between the origin and the point B'

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

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

O (0,0) and B'(2,-3)

substitute

$d=\sqrt{(-3-0)^{2}+(2-0)^{2}}$

$d=\sqrt{13}\ units$

step 3

Find the scale factor of the dilation

The scale factor is equal to divide the length of segment OB' by the length of segment OB

$\frac{\sqrt{13}}{\sqrt{325}}=\frac{1}{5}$

Please help algebra 1 question

vlada-n [284]

Answer:<u> x=-3</u>

<u></u>

Step-by-step explanation:

2x(3x+9)=-2(2x+6)

2/3 (3x)+2/3(9)=(-2)(2x)+(-2)(6) distrubute this

2x+6=-4x+-12

2x+6=-4x-12. subtract 4 on both sides

2x+6=-4x-12

2x+6+4x=-4x-12+4x

6x+6=-12

6x+6-6=-12-6

6x=-18

6x/6=-18/6

=x=-3

Hoped this helped sorry it took me forever:)
