Find the coordinates of m' after a reflection across the line y= -1 and then across the x=-2.

  M' = (-1, 3)

Step-by-step explanation:

The two reflections are equivalent to a reflection across the point P = (-2, -1), which becomes the midpoint of the line segment MM'. The coordinates of M' can be found from ...

  M' = 2P -M = 2(-2, -1) -(-3, -5) = (-4+3, -2+5)

  M' = (-1, 3)

_____

The formula used comes from the formula for the midpoint:

  P = (M +M')/2

  2P = M + M' . . . . multiply by 2

  M' = 2P - M . . . . .subtract M

how am i supposed to answer

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
