A. When you equalize two equations, geometrically you are trying to find the intersection point of them, i.e. find the common point of them. So the x coordinate of the intersection point is basically the solution.
B. You can simply plug in numbers from -3 to 3 and list the values by yourself.
C. Graphically, draw each equation, and find the x coordinate of the intersection point.
FYI, the solution is x = 1/3
Answer:
20
Step-by-step explanation:
count the sides of the boxes for each side of the shape
N is -4 because -4x2=-8 and -8+3=-5
569/x=100/18
multiply both sides of the equation
569=5.55556
now we divide
569/5.55556
102.42=x
18% of 569=102.42
