The wheel was first documented as being used in Mesopotamia (Iraq today) in 3500 B. C. The first steam powered vehicle that used wheels was invented in 1672 A. D. How long did it take for the wheel (from being invented) to get pushed by a machine?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

a reflection across the x axis and a 90 degree rotation left and right.
