Answer: x=-y+8 and x=y+6
Step-by-step explanation:
Because there's no picture provided, I can just give two points in order to formulate the equation using the point-slope formula. The x is in years while the y is in percentage. Suppose point 1 is (2, 35) and point 2 is (7,80).
Point Slope Formula: y - y₁ = [(y₂ - y₁)/(x₂ - x₁)](x - x₁)
Substituting,
y - 35 = [(80 - 35)/(7 - 2)](x - 2)
y - 35 = 9(x - 2)
This would be 4cm... Since all the sides are equal and you have the distance between CB you can calculate the distance of all other sides
B, about 30 fewer. The amount sold in Mar. is 70 and the amount sold is May rounds to 40, and 70-40=30
