Answer: 85
Step-by-step explanation: 15 × 6= 90 - 5= 85
Add them all up, and divide by 10 so 29+38+39+26+29+29+39+77+38+29 which is 33.5
Since A‘(-1,1) is on the line y=-x, reflecting it about the line doesn't change its coordinate, so A's coordinate is (-1,1). Reflecting B'(-2,1) about y=-x switches both the sign and the number of x and y, so B=(-1,2), and C'(-1,0) becomes C(0,1). Drawing out the graph with the points and the line helps.
I think the answer is going to be a
Answer:
I think that the first one is not a rhombus but the last two are.
