Step-by-step explanation:
A linear graph has an equation of the form:
y = mx + b,
where y and x are variables, m is the slope (rate of change) of the graph and b is the y intercept (value of y when x is 0).
Given that:
2x -2y = 4 , 3x + 2y = 6
The matrix form of the equation is:
AX = B
Answer:
≈ 38.64 units
Step-by-step explanation:
The length of arc s is calculated as
circumference of circle × fraction of circle
The central angle subtended by arc s is 360° - 114° = 246° then
arc s = 2πr ×
= 2π × 9 ×
= 18π ×
≈ 38.64 ( to 2 dec. places )
