Answer:
x = 2, y = 3
Step-by-step explanation:
5x – 4y = -2
2x + 4y = 16
<em></em>
<em>Solve by elimination. (-4y and +4y gives 0)</em>
7x = 14
x = 2
<em>Substitute 2 in one of the equations in order to find y.</em>
5(2) - 4y = -2
10 - 4y = -2
-4y = -12
y = 3
x = 2, y = 3
hope this helps!! p.s. i really need brainliest :)
Your question is unclear, can you elaborate more?
Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as

x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is

Therefore, the scale factor is
and the correct option is D.
1.) 6.50(m)= x
2.) x= 6.00m + 50
3.)6.50m-0= x
