Answer:
B
Step-by-step explanation:
If we start with the assumption that segment DE is parallel to segment BC, then we the similarity condition that:
triangle ABC is similar to triangle ADE
For this to be true, the ratio corresponding sides of the two triangles must be equal. So:
5/8 =? 6/10
But
5/8 =/= 6/10
So, DE is not parallel to BC
Answer:
the answer is B, because x+x+x is equal to 3×x which is 3x
Answer: 4) y = -1/3x² + 2x - 1
Step-by-step explanation:
Given :
y = 
+ 2
Expanding (x-3)² will give :
- 6x + 9
substituting into the function , we have :
y = ![( [tex]x^{2}](https://tex.z-dn.net/?f=%20%28%20%5Btex%5Dx%5E%7B2%7D)
- 6x + 9 ) + 2
Expanding , we have
y = + 2x - 3 + 2
y = + 2x - 1
Answer:
y = x - 5
