(21-3)times(7+4)
If you mean: x^2+15-3x then its value is 19 when x equals 4
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
The vertex of this parabola is at -5 -2 When the x-value is -4 the y-value is 2. The coefficient of the squared expression in the parabola's equation is 4. y = a(x - h)2 + k; (h, k) = (-5, -2); (x, y) = (-4, 2) 2 = a[-4 -(-5)]2 - 2, add 2 to both sides 4 = a(-4 +5)2 4 = a(1)2 4 = a
It is an algebraic expression that can be simplified depending on the plus or minus value of 4
The expression (2x - 4) represents a linear equation where the value depends on the variable (x). To determine a specific value, you need to substitute a specific value for (x). For example, if (x = 3), then (2x - 4 = 2(3) - 4 = 6 - 4 = 2). Without a specific value for (x), the expression remains variable.

-4 (-9 +5 = -4)
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
The value of x is the unknown variable and the given expression can be simplified to: 4x-15
Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
That depends on the value of x in the given expression
