--------------------------------------------
C represents positive number
Hope this helps!! :)
Please let me know if you have any question
It should be the top left because the shaded area is below (or less than) the line -3/4x +1 and greater than the other line
Answer:
(-5,3)
Step-by-step explanation:
The point (5,7) translated down 4 units gets to the point (5,3). If you reflect it over the y-axis, the x-coordinate becomes negative, and the y-coordinate stays the same. This gets you the point (-5,3)
Hope it helps and is correct!
Answer:
BC = 
= 49 unit
Step-by-step explanation:
The given as AC is a line with B as its mid point
AND ,
AC = 8x + 15
AB = 3x + 4
BC = 4x - 1
∵ AC = AB + BC
Or, 8x + 15 = ( 3x + 4 ) + ( 4x - 1)
Or, 8x + 15 = 7x + 3
Or, 8x - 7x = 3 - 15
∴ x = - 12
SO, AC = 8x + 15 = 8 × ( - 12) + 15 = - 81
Or, AC = 
= 81 unit
And ,AB = 3x + 4 = 3 × ( - 12) + 4 = - 32
Or ,AB = 
= 32 unit
Similarly BC = 4x - 1 = 4 × ( - 12) - 1 = - 49
Or, BC = = 49 unit Answer
