Answer:
7.7
Step-by-step explanation:
we basically follow the BEDMAS rule
1st we workout the bracket (7-2)=5
2nd the exponent 3^2=9
3rd the multiplication (7-2) . 4 = 5 . 4 = 20
4th addition 9+20=29
5th step is subtraction 29-6=23
the final step is dividing 23 by 3, which will become 7.7
A reflection across the x-axis has the rule:
(x,y)→(x,-y).
Then:
- A(-1,-1)→A'(-1,1),
- B(0,1)→B'(0,-1),
- C(4,2)→C'(4,-2),
- D(6,0)→D'(6,0),
- E(3,-3)→E'(3,3).
Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
