if you plot these two functions (which are both straight line graphs), you will see that they intersect at one point. The value of x you are trying to find is the x-coordinate of the point of intersection (see attached graph).
x + 2 = 2x + 3
subtract x from both sides: 2 = x + 3
subtract 3 from both sides: -1 = x
Therefore, x = -1
Sub x = -1 into either of the functions to get the y-coordinate of the point of intersection:
since he earns x dollars every seven days, to get the amount he earns, you divide that amount by 7 and for Lee, she gets twice as much so you multiply Michael's amount by 2
Angle A = 30 and its complement would be 60. This is because both angles must equal 90 degrees, and 30 + 60 = 90. Also in the directions it states Angle A must be half of its complement. 30 is half of 60. Sorry I don’t have any work, I just did it in my head!
