Answer: -9

Step-by-step explanation:

So if f(x) is given, that is 2x-5, then to find f(-2) we need to substitute the value of x by -2

Therefore, f(-2) is,

2(-2)-5

= -4-5

= -4+-5

=-9

Answer:

B. ΔDEF ≅ ΔSRU

Step-by-step explanation:

Reflection changes corresponding vertices from CCW order to CW order. Vertex D gets reflected to (-6, 4), then translated to (-3, 0). After this transformation, its image is vertex S. The vertices in CW order from S are SRU. Hence, ΔDEF ≅ ΔSRU, matching choice B.
