Answer:
C
Step-by-step explanation:
A&B are wrong because they imply that x can equal 250, which it can't, it has to be less than 250 so the max x can be is 249.
D is wrong because it is talking about greater than which it is not. It is less than
C is correct
y=400+50x
y=300+25x
Step-by-step explanation:
x is the number of minutes and y is the total cost
Answer:
1) The reflection of a preimage (x, y) across the line y = x gives the image (y, x)
Therefore, the the coordinates of the points L, M, and N interchange to give an image of the triangle that is apparently rotated 90° clockwise, on the opposite quadrant and equidistant from the line y = x
2) Where the line segment drawn from point L to the reflecting line is horizontal, and the line segment drawn from point L to the reflecting line is horizontal, the two line segment will be of the same length and separated vertically separated vertically by a distance equal to the sum of the absolute values of the x and y coordinates of the point L
When the line segment from point L is drawn perpendicular to the reflecting line, the line segment from point L' drawn perpendicular to the reflecting line will meet the the perpendicular line segment at the same point of intersection of the line from the point L and the reflecting line
3) Yes
4) This is so because, reflection of a preimage unto an image is a form of rigid transformation, therefore, the effect of the transformation operation will be similar when each point is individually considered.
