Ch3L3 Linear Equation--y=mx/Direct Variation Flashcards
Sam baked 3 cakes in two and half hours. Assume that the number of cakes baked varies directly with the number of hours. Write an equation to represent this.
A color printer can print 36 pages in 3 minutes. If the number of pages varies directly with the time, what is the equation for this?
A new compact car can travel 288 miles on nine gallons of gas. The distance driven in miles varies directly with the number of gallons of gas. Write an equation in y = mx form to represent this. And what does m here mean?
Sam’s earning varies directly with the number of packages he delivers. If Sam can earn $15 for delivering 3 packages. Write an equation in y = mx form to represent this. And what does m here mean? How much can Sam earn if he delivers 12 packages?
The weight of an object on Mars varies directly with its weight on Earth. An object that weights 50 pounds on Mars weights 150 pounds on Earth. Write an equation to represent the relationship between the weight on Mars and weights on Earth of object. And if Richard weighs 300 pounds on Earth, how much does he weigh on Mars?
