1. The DCP Colts Football team scored 55 points at the last game. The number of field goals was 1 more than twice the number of touchdowns. The DCP Colts Football Team earned 7 points for each touchdown and 3 points for each field goal. What is the best system of equations that represents this situation? note: Let t = # of touchdowns and Let f = # of field goals (10 Points) t = 2f + 1; 7t + 3f = 55 f = 2t + 1; 7t + 3f = 55 t = 2f + 1; 3t + 7f = 55 f = 2t +1; 3t + 7f = 55

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.
