The equation that models Amanda’s situation using distance, d, from the streetlight as a linear function of walking for t- seconds is d = 4t + 6.
An equation basically means a mathematical statement including variables and operators that shows that two expressions are equal. Any equation can be solved using the PEMDAS rule. where P stands for Parenthesis, E stands for Exponents, D stands for Divide, M for Multiplication, A for Addition and S for Subtraction.
The distance is given by d, and the time is t.
Amanda walks at a rate of 4 feet per second, so after t seconds she will walk 4t distance.
She starts at a distance of 6 feet from the streetlight, so the equation will be,
d = 4t + 6
Therefore, the equation that models Amanda’s situation using distance, d, from the streetlight as a linear function of walking for t- seconds is d = 4t + 6.
