He charges $25 per lawn and $20 per driveway. Let x represent the amount of money that Jameson can save so that his parents will match the amount. Let L represent the number of lawns he mows, and D represents the number of driveways he shovels. Which of the following inequalities need to be part of the system? Select all that apply. x<=2000 x=>2000 25l+20d=x 20l+25dx
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
