Please follow and perform the 4 steps bellow. (i) Match each equation to a situation. (you can copy and paste the equation to the situation that matched.) (ii) Tell what each number means in context. (iii) Tell what the variable stands for. (iv) Solve the equation. Equations: 0.9x – 10 = 116 14x + 3x + 150 = 1102 1500 – 120x = 660 Situations: (A) You deposit money in the bank. You withdraw the same amount every month, ending with a certain amount. (B) A store is having a sale on car stereos. First a certain percentage is taken off the price, and then the price is reduced by a fixed number of dollars, resulting in a purchase price. (C) Your family is installing carpet on a fixed budget. The costs include the cost of the carpet per square yard, the cost of the padding per square yard, plus a fixed installation fee.
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.
