Answer:
155 minutes
Step-by-step explanation:
1. Find the total available "computer time": 4 hours * 12 computers= 48 hours
2. Split this among all of the students: 48 hours/25 students= 1.92 hours
3. Convert to minutes: 1.92 hr/student * 60 minutes ≈ 155 minutes/student
When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .
So the final answer is (-1,-2) .
Answer: 13
Step-by-step explanation:
5+2x
When x=4
5+2(4)
5+8
= 13
A the first answer because the triangles are the same they are just flipped
