Hi there!
I believe the dilated number is 3.
If you look at A figure... there a 2 squares and 4 1/4ths which makes an entire square. Once that is added you have three.

Happy to help!

3 is the scale factor you would use to dilate Figure A to Figure B.

Consider the quadratic function f(x)=2x^2-8x-10
Slav-nsk [51]

Answer:

f(x) = 2x² - 8x - 10.

This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:

a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex

b) for x =  2, f(x) = f(2) = - 18 (component of y of the vertex)

c) VERTEX(2, - 18)

d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144

Hope this helps! :)

Solve the simultaneous equations<br> 5x+2y=25 <br> 5x-y=10
Pavlova-9 [17]

<em>5x + 2y = 25;</em>

<em>5x + 2y = 25;5x - y = 10;</em>

5x + 2y = 25;

5x = 10 + y;

(10 + y) + 2y = 25;

5x = 10 + y;

10 + 3y = 25;

5x = 10 + y;

3y = 15;

5x = 10 + y;

y = 5;

5x = 10 + y;

y = 5;

5x = 10 + 5;

y = 5;

5x = 15;

y = 5;

x = 3.

Answer: (3; 5).

12 + 3m = 18 x 2

12 + 3m = 36

3m = 36 - 12

3m = 24
