Step-by-step explanation:
- An airplane leaves Los Angeles for Denver at a speed of 430 mph. Thirty minutes later another plane going from Denver to Los Angeles leaves Denver, which ... So to begin with plane 1 got a 30 minute head start, so since it was going at 430 miles per ... LOS ANGELES - DENVER...430 miles/hour, x hours.
Using linear function concepts, it is found that:
- a) It costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
- b) f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.

A <em>linear function </em>has the format given by:

In which:
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
The equation for the cost of h kilowatt hours (kWh) of electricity used in excess of 250 kWh is of:

Item a:
- The slope is of
, which means that it costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
Item b:

250 + 90 = 340.
f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.
