Octagon is 309.02cm²
Pentagon is 172.05in²
9u-9t=18
original no. is 10t+u
reversed no. is 10u+t
so its (10u+t)-(10t+u)=18
which gives 9u-9t=18
Step-by-step explanation:
a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.
3). y = -1/3x + 5
4). y = -1x +5
Slope intercept form: y = mx + b
m = slope
b = y intercept
