the new problem would be 9(7)-2(7) when you substitute 7 for x.The answer is 63-14= 49
So your answer is 49(:
The expression in the question "y -2x" is not a function.
It isa linear expression,a binomial expression,an algebraic expression,a polynomial expression.
2(2x + 3)
(x + 7)(x - 5)
If you mean x2 + 2x + 15: Then the answer would be that it's a quadratic expression with no factors. If you mean x2 - 2x + 15: Then it can be factored out to: (x - 5)(x + 3) If you mean x2 + 2x - 15: Then it can be factored out to: (x + 5)(x - 3)
X = 7 9x - 2x = 49
X = 6 5x + 2x = 42
It's 9 x 7 minus 2 x 7. So its 63 - 14.
X = 7 9x - 2x = 49
Evaluate the expression below when x = 2.3x2-2x+4
3(10x + y) + 2x + 7y (multiply the 3 through the parentheses then combine like terms) = 30x + 3y + 2x + 7y = 32x + 10 y Evaluate an expression for some values of x and y, means to substitute those values into the expression, such that when x = 3 and y = 1 the value of the given expression is 106: 32x + 10y = 32(3) + 10(1) = 96 + 10 = 106
To evaluate expressions by substitution, first identify the variable(s) in the expression and determine their corresponding values. Replace each variable in the expression with its given value. Finally, perform the necessary arithmetic operations to simplify the expression and obtain the final result. For example, if the expression is (2x + 3) and (x = 4), substitute to get (2(4) + 3), which simplifies to (8 + 3 = 11).

The expression (6 - 2x - y) represents a mathematical equation involving three variables: (6), (2x), and (y). It can be interpreted as a linear expression where (2x) and (y) are subtracted from 6. To evaluate it, you would need specific values for (x) and (y). Without those values, it remains an expression rather than a numerical answer.
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
The expression (2X + 3 - X) simplifies to (X + 3) by combining like terms. If you're looking for a specific value, you would need to substitute a value for (X). Otherwise, the simplified expression is (X + 3).
Yes. Any problem you see with variables (any letter in a problem) is an algebraic equation.
