Answer:
y= -2x/3+8
Step-by-step explanation:
find 2 points: (0,8) and (6,4)
substitute in y=ax+b
8=0a+b
b=8
4=6a+b
4=6a+8
6a=-4
a=-2/3
We have 2x + 4x + 5x = 33 so 11x = 33 and x 3.
The children are 6, 12 and 15
Answer:
D(2,2)
Step-by-step explanation:
The diagonals of a parallelogram gram bisects each other.
Therefore E is the midpoint of AD.
Let the coordinates of D be (a,b).
By the midpoint rule:

This implies that:

This implies that:


Use the zero product property
x - 3 = 0, and x - 2 = 0
x = 3, and x = 2
Solution: (3,0) and (2,0)
