To identify the coefficient of x in the expression 7x^2 + 5x - 3, we need to understand what a coefficient is. A coefficient is the numerical factor that multiplies a variable in a term. Step 1: Identify the terms in the expression. The expression is 7x^2 + 5x - 3. The terms are 7x^2, 5x, and -3. Step 2: Locate the term that contains the variable x (raised to the power of 1). The term containing x is 5x. Step 3: Identify the numerical factor in front of x in that term. In the term 5x, the numerical factor multiplying x is 5. Therefore, the coefficient of x is 5. Comparing this with the given options: A. 7 (This is the coefficient of x^2) B. 5 C. -3 (This is the constant term) D. 2 (This is the exponent of x in the first term) The correct option is B. The final answer is B. 5. What's next? 📸
