Answer:
y = -3x + 21
Step-by-step explanation:
(5,6)
y = mx + b
6 = -3 × 5 + b
solving for b
b = 6 - (-3)(5)
b = 21
Therefore,
y = -3x + 21

Answer:
x = 13
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here A = 55, h = 5. b₁ = x, b₂ = 9, then
× 5 × (x + 9) = 55
2.5(x + 9) = 55 ( divide both sides by 2.5 )
x + 9 = 22 ( subtract 9 from both sides )
x = 13
Control = group with no music / maybe no variable?
Manipulated/independent variable = Number of tomatoes being grown
Dependent/responding = Number of tomatoes produced by each plant
Conclusion = Use four parts... Was your hypothesis correct or not and why...Cite numbers/evidence from experiment.... Were the results reliable?.... any improvements to be made
