4x + 7y - 9
The expression 4x + 7y - 9 is a linear expression in two variables (x and y). It represents a straight line in a coordinate plane. The coefficients 4 and 7 are the slopes of the line, and the constant term -9 is the y-intercept (the point where the line intersects the y-axis).
The expression 4x + 7y - 9 is a linear expression. Linear expressions represent lines on a graph and consist of terms that involve variables raised to the power of 1 (no exponents). It can be simplified or evaluated depending on the context of the problem. If you have a specific question or task related to the expression, please let me know so I can assist you further.
The expression 4x + 7y - 9 represents a mathematical expression with variables x and y. To simplify or evaluate this expression, you need specific values for x and y.
If you have specific values for x and y, you can substitute them into the expression and perform the necessary calculations. For example, if x = 2 and y = 3, you would substitute these values into the expression: 4(2) + 7(3) - 9.
By following the order of operations (PEMDAS/BODMAS), you would multiply 4 by 2, multiply 7 by 3, and then subtract 9. The result of this calculation would give you the value of the expression when x = 2 and y = 3.
However, without specific values for x and y, 4x + 7y - 9 remains as an algebraic expression that cannot be further simplified or evaluated.
